THIN SOLID FILMS 591 245 - 249 2015

Language：English Publisher：ELSEVIER SCIENCE SA

Ilmenite-hematite solid solution (Fe2-xTixO3) is one of the candidates for high-temperature magnetic semiconductors. Well-crystallized and epitaxially formed Fe2-xTixO3 films on alpha-Al2O3 (11 (2) over bar0) single-crystalline substrates were tried to fabricate by using reactive sputtering technique. The detailed structural properties of (11 (2) over bar0)-oriented epitaxial Fe1.4Ti0.6O3 films were analyzed by using transmission electron microscope (TEM). The films showed large magnetization and typical semiconductive conduction at room temperature. However their anisotropic properties were rather small than expected, though the films had good crystallinity with preferred orientation. The TEM observations clearly revealed that the (11 (2) over bar 0)-oriented Fe1.4Ti0.6O3 films on alpha-Al2O3(11 (2) over bar0) were partly composed of the (0001)-oriented grains. Formation of the (0001)-oriented grains could reduce the anisotropic properties of the (11 (2) over bar0)-oriented films. (C) 2015 Elsevier B.V. All rights reserved.

We report the synthesis and magnetic properties of the AgI-intercalated misfit-layer cobalt oxide Bi Ca Co O . The AgI-intercalated Bi Ca Co O was prepared by the guest exchange reaction from the I -intercalated one. SEM-EDX analysis exhibited the stoichiometric ratio of Ag/I and the guest concentration as (AgI)Bi Ca Co O on the basis of Co = 2. After the AgI intercalation, the lattice parameter along the c-axis calculated from X-ray diffraction patterns was 21.68 Å, which was drastically increased not only from the non intercalated host phase (14.68 Å) but also from the I -intercalated phase (18.08 Å). After the AgI intercalation, magnetic susceptibility measurements revealed that the antiferromagnetic Weiss temperature and the effective magnetic moment in Co ion simultaneously decreased compared with the non-intercalated host compound. © 2008 Elsevier B.V.

Characterization of biogenic iron oxide sheaths produced by Leptothrix ochracea (L. ochracea) was investigated. The sheaths had average inner- and outer-diameters of 1.08 ± 0.15 and 1.35 ± 0.14 μm, respectively. Their length ranged from 10-2000 μm. Outer and inner surface of each sheath were composed of fibrous and spherical particles, respectively. The width of fibrous particles was approx. 20 nm, while the diameter of spherical particles was 20-120 nm. The chemical composition of the sheaths was Fe: Si: P = 73: 22: 5 with the exception of H and O. The sheaths had similar structure to that of 2-line ferrihydrite.

Ilmenite-hematite solid solution (Fe Ti O ) is one of the candidates for practical magnetic semiconductors with the high Curie temperature (T ). We have successfully prepared well-crystallized and epitaxial Fe Ti O films by using a reactive helicon plasma sputtering technique. The structural characterizations indicated that the films had the order structure (R over(3, -) symmetry), where Ti- and Fe-rich layers were stacked alternately along the c-axis, without any secondary phase. The subsequent annealing of the films in vacuum at 700 °C promoted the R over(3, -) symmetry. Only the films having the good R over(3, -) symmetry had large ferrimagnetic moments at room temperature. The resistivities of the films clearly showed semiconducting behavior, i.e., logarithmic resistivity showed a monotonous increase with increasing the inverse temperature. The minimum room temperature resistivity of the films was about 10 Ω cm. From the Hall effect measurement all films had n-type conduction. The carrier concentration was estimated to be about 10 -10 cm , depending on the annealing conditions. © 2006 Elsevier B.V. All rights reserved. 2-x x 3 C 1.4 0.6 3 -1 19 21 -3

Materials Letters 61 ( 17 ) 3774 - 3777 2007

The polymeric complex method has been employed to investigate the effects of substitution by lanthanum into hematite powder on structures, morphology and color tone properties. X-ray diffraction measurements evidenced the existence of Fe La O at 1000 °C-1200 °C by shifting peaks to lower angles. At higher temperature, lattice parameters and cell volume were found to expand due to the incorporation of La ion into the hematite in the range 301.98-303.87 Å . Crystalline size decreased when increasing the amount of La ion in the reaction process. Suppression of particle growth was observed by the Field Emission Scanning Electron Microscopy studies at higher temperatures. Brighter yellowish-red color than that of pure hematite was obtained and it grew into deeper color tone rapidly by increasing the amount of La ion into the hematite. © 2007. 2 - x x 3 3+ 3 3+ 3+

Some features of characteristic iron oxide sheaths which the iron oxidizing bacteria Leptothrix ochracea (L. oceracea) formed were studied in order to make clear their morphology microstructure, chemical composition, and crystal structure through scanning electron microscopy (SEM), energy dispersive X-ray spectrometry (EDX), and X-ray diffraction (XRD). Each sheath was a hollow tube with average outer and inner diameters of 1.1 and 1.4 μm, respectively. Their length ranged from 10 to 200 μm and the aspect ratio was 10-200. Each sheath was constructed by very small particles with a diameter of less than 100 nm. The hollow sheaths were mainly composed of Fe and O with small amounts of Si and P. The chemical composition analyzed by EDX was roughly Fe:Si:P=80:15:5 with the exception of O. XRD measurement revealed that crystal structures of the sheath were similar to that of 2-line ferrihydrite. The sheath showed spin-glass-like magnetic properties. © 2006 Elsevier B.V.

Cerium doped hematite powders obtained by polymeric complex method following the hydrolysis of FeCl · 6H O and Ce(NH ) (NO )6. X-ray diffraction pattern of cerium doped samples obtained at 1000°C̃ 1200°C for two hours in air revealed some solubility of cerium ion in α-Fe O over the composition range of 5%̃15 at% that were characterized by the shifting of X-ray diffraction peaks compared with the internal silicon standard. X-ray Photoelectron Spectra investigations revealed the existence of Ce ion at higher temperature. Unit cell parameters were found to expand due to the incorporation of cerium ions into the hematite lattice. Field Emission Scanning Electron Microscopy studies showed that the growth of particles was suppressed in the appearance of cerium ions into the α-Fe O lattice. Fe Ce O exhibits much lower magnetization due to the incorporation of non-magnetic cerium ions into the α-Fe O . Spectroscopy measurement evidenced that cerium doped hematite samples exhibited brighter yellowish red color tone than that of pure α-Fe O . 3 2 4 2 3 2 3 3+ 2 3 2-x x 3 2 3 2 3

Ceramic Transactions 196 85 - 90 2006

Iodine intercalation and deintercalation of a Sr-free Bi-based cuprate, Bi (La,Na) CuO:, have been investigated. It has been confirmed by powder X-ray diffraction and thermogravimetric analysis that the stage-1 iodine-intercalated compound Bi (La,Na) CuO l with x=1.0 was formed. As in the case of a Bi (Sr,La) CuO: (Bi-2201) specimen, expansion of the c-length of the stage-1 iodine-intercalated compound was 3.6 Å, compared with one half that of host compound. After deintercalation of the intercalated iodine, the stage-1 iodine-intercalated compound returned reversibly to the host compound. The powder X-ray diffraction pattern showed the formation of the intermediate phase containing a certain amount of iodine, not assigned to the stage-2 intercalated compound, during the deintercalation. Neither host compound nor iodine-intercalated compound exhibited superconductivity down to 2 K. 2 2 2 2 7 x 2 2

Ceramic Transactions 196 497 - 503 2006

In this study, low temperature preparation conditions for Co Z (3BaO·2CoO·12Fe O ) particles were investigated by using alkaline halide method. The obtained particles were characterized by using X-ray diffraction and scanning electron microscopy techniques. Many factors such as the metal compositions, heating temperature, heating and cooling rates, and amount of flux reagents were changed for the preparation. The X-ray diffraction analysis indicated that (1) the metal compositions, (2) flux reagent, and (3) heating rate were important to obtain Co Z at low temperature using the alkaline halide method. Nearly monophasic Co Z was formed under the following conditions: metal compositional ratio of Ba : Co: Fe = 3.0 : 1.5 : 24 with 10wt% BaCl flux and rapid heating to 1200 °C for 6 hours. Co Z powders mixed with an EPDM rubber were pressed to a sheet form. The electromagnetic properties of rubber sheets were examined to apply to use as an electromagnetic wave absorber. 2 2 3 2 2 2 2

We have successfully prepared Carbon/Fe-Co alloy composites starting from metal organic precursors synthesized by polymerized complex method. The carbon/Fe-Co alloy composites were obtained after the carbonization of the precursors heat-treated at ambient pressure and lower temperatures ranging from 500 to 700°C in N 2 gas flow. Crystalline sizes of both carbon matrix and Fe-Co alloy particles were determined by X-ray diffraction measurements as a function of the Co concentration and the carbonized temperature. The alloy particles were widely dispersed in the carbon matrix and the particle size carbonized at 600°C was about 20-50nm observed by scanning electron microscopy. The composite carbonized at 600°C had very small coercivity of 14 Oe and exhibited relatively large permeability spectra at frequency of GHz range.

Journal of Materials Science 40 ( 16 ) 4169 - 4172 2005

A stable precursor for CoFe O thin film was prepared by sol-gel technique from the aqueous solution of FeCl •6H O and CoCl •6H O. Sol was deposited on a naturally oxidized silicon-substrate by spinning technique (2000 rpm) and heat treated at different temperatures ranging from 700 to 1100°C. Thickness of the films was controlled in the range of 400-500 nm and all the films were characterized by using XRD and SEM. The effects of temperature and the composition on the formation of CoFe O thin film were also studied. Films obtained at relatively lower temperature showed multi-phases of α-Fe O , CoFe O and CoO while the formation of CoFe O phase increases with increasing temperature. Furthermore, the composition of the solution in mol% has great role on the formation of CoFe O films and the film containing 50 mol% of Co exhibited CoFe O mono-phase. Surface morphology of the films was studied by scanning electron microscope (SEM). Magnetic properties of the films, studied by using vibrating sample magnetometer (VSM), showed relatively high saturation magnetization (8.04-22.21 kWb/m ) as well as high coercivity (44.59-63.30 kA/m). Saturation magnetization also increases with increasing heat treatment temperature. © 2005 Springer Science + Business Media, Inc. 2 4 3 2 2 2 2 4 2 3 2 4 2 4 2 4 2 4 2+ 2

Fine particles of cerium substituted hematite with different compositions were prepared by the sol-gel method from the aqueous solution of their corresponding metal salts. Mixed hydroxides of Fe and Ce were obtained by reacting aqueous NH with the aqueous solution of FeCl and Ce(NH ) (NO ) at pH 2.5-3.0) and they were heat treated at different temperatures between 400 and 1200°C in air for 2 h to get the mixed oxide product. Thermal analysis and X-ray diffraction studies revealed the coexistence of Fe O and CeO phase separately up to 900°C, and covalent interaction between them above 1000°C, which was evidenced by the shifting of the XRD peaks. Unit cell parameters and the cell volumes (V) of the samples derived between 1000 and 1200°C were found to be in the range a = 5.045-5.048 ± 0.007 Å, c = 13.774-13.815 ± 0.041 Å and V = 303.608-304.874 Å respectively. It was observed that both the lattice parameters and the cell volumes were higher than that of the pure α-Fe O (a = 5.036 Å, c = 13.749 Å, V = 301.976 Å ) system. The expansion of lattice parameters further supported the incorporation of the large Ce ion into the α-Fe O matrix. The lattice parameter increased with increasing Ce ion loading. FESEM studies showed the growth of the particles with increasing temperature though it was suppressed due to the presence of Ce ions as compared to the pure system. © 2005 Elsevier B.V.

Spinel-type Co Fe O (x=0-0.5) thin films (∼450 nm thickness) on SiO glass substrate were prepared by the sol-gel method using spinning technique (2000 rpm) from the aqueous solution of FeCl .6H O and CoCl .6H O. All the films were heat treated at different temperatures ranging from 700 to 1100°C. The films were structurally characterized by using the X-ray diffraction technique (XRD), and the morphology was studied by field emission scanning electron microscope (FESEM). The effects of temperature and the composition ([Co ]/ [Fe ] ratio) on the formation of Co Fe O thin films were also studied. The films obtained at relatively low temperature showed mixed phases of α-Fe O , CoO, along with CoFe O , while the formation of the CoFe O phase increases with increasing temperature. Furthermore, the composition of the solution in terms of [Co ]/[Fe ] plays a great role on the formation and magnetic properties of the films. The magnetic properties of the films, studied using vibrating sample magnetometer (VSM), showed relatively small saturation magnetization, and coercivity was observed to be low as compared with that of other reports. Saturation magnetization also increases with increasing heat treatment temperature. © 2004 Elsevier B.V. All rights reserved. 1+x 2-x 4 2 3 2 2 2 1+x 2-x 4 2 3 2 4 2 4 2+ 3+ 2+ 3+

Materials Letters 59 ( 4 ) 468 - 472 2005

Nanograined hexagonal barium ferrite (BaFe O ) thin films have been developed on naturally oxidized Si substrates by sol-gel technique using aqueous solution of metal chlorides. Coated films were heat treated at different temperatures ranging from 450 to 900°C, and all the films were characterized by using X-ray diffraction (XRD), inductive coupled plasma (ICP) spectroscopy, and field emission scanning electron microscopy (FESEM). The effects of temperature on the formation of BaFe O thin film were studied, and it was observed that hexagonal barium ferrite thin films with grain sizes of about 50 nm were formed above 700°C. Study on the magnetic properties of the films by vibrating sample magnetometer (VSM) showed that films exhibited large saturation magnetization and high coercivity in the range 247-355 emu/cm and 2.70-4.22 kOe, respectively, while the Curie temperatures (□ ) were in the range 443-457°C. The effects of temperatures on the magnetic properties were also studied. © 2004 Elsevier B.V. All rights reserved. 12 19 12 19 c 3

Unique magnetic and electric properties of solid solutions of ilmenite (FeTiO ) and hematite (α-Fe O ) can be expected for new electronics, optics and spintronics applications. We have successfully prepared well-crystallized and epitaxial Fe Ti O (001) films on α-Al O (001) substrates by reactive helicon plasma-sputtering technique. Structure, magnetic and electric properties of the films were seriously dependent on both the oxygen pressure and the substrate temperature during the sputtering deposition. The subsequent annealing of the films in vacuum at high temperature (600 °C) promoted the order (R3̄) structure of Fe Ti O , where the Ti and Fe ions occupied the cation sites alternatively along the c-axis. Only the films having the R3̄ symmetry had large ferrimagnetic moments at low temperature (78 K), although the magnetization values were depending on not only the order parameter between the R3̄ and the R3̄c structures but also the oxidization states of Fe ions in Fe Ti O . The film prepared at an oxygen partial pressure ratio of 1.4% and substrate temperature of 400 °C had considerably large spontaneous magnetization of 275 emu/cm at 78 K after the subsequent annealing at 600 °C. However, highly oxidized nonstoichiometirc Fe Ti O films with the R3̄c symmetry could not give the ordered structure with the R3̄ symmetry. © 2004 Elsevier B.V.

The effect of Co ion on the magnetic properties of the sol-gel derived cobalt ferrite thin films (400 nm thickness) was studied. Films with different solution composition ([Co ]/[Fe ] = 0.5-1.0) were deposited on a Si substrate from the precursor containing an aqueous solution of FeCl ·6H O and CoCl · 6H O. Deposited films were heat treated at different temperatures (700-1100 °C) and were characterized by X-ray diffraction using Cu Kα radiation. The films containing a nonstoichiometric α-(Fe Co ) O phase were obtained in addition to a small amount of CoO at relatively lower temperatures. With increasing heat treatment temperature, nonstoichiometric α-(Fe Co ) O was decomposed to stoichiometric α-Fe O and the CoFe O phase was intensified. Only the films obtained from the solution enriched with Co showed the single phase of CoFe O , though the Co to Fe content ratio analyzed by inductive coupled plasma spectroscopy (ICP) and energy dispersive X-ray spectroscopy (EDX) was nearly consistent with that of the starting solutions. The study of surface morphology of the films by using field emission scanning electron microscope (FESEM) showed that films were homogeneously distributed throughout the surface of the substrate and the grain sizes were in the range of 60 to 140 nm. Magnetic properties of the films, including the Curie temperature, were studied by using a vibrating sample magnetometer (VSM) and conversion electron Mössbauer spectroscopy (CEMS). The Curie temperature and the magnetic hyperfine fields of the films slightly decreased with increasing molar ratio of the Co and Fe ions while the saturation magnetization reached a maximum value with the film composition of x = 0.28. 2+ 2+ 3+ 2+ 3+ 3 2 2 2 1-x x 2 3 1-x x 2 3 2 3 2 4 2 4

Well-crystallized Y-type hexagonal ferrite films with highly c-axis orientation were successfully prepared on Ag, Au and Pt substrates by polymerized complex method. The films prepared on Ag had considerably low formation temperature of 800°C, while those on An and Pt were formed at above 1000°C. The films had large in-plane magnetic anisotropy, with small coercivity. Hexagonal grains structures were developed on the substrates. © 2003 Published by Elsevier B.V.

Epitaxial FeTiO (001) films were prepared on α-Al O (001) substrates by helicon plasma sputtering technique. Structure and magnetic properties of FeTiO film were largely dependent on the residual oxygen pressure (Po ) during the sputtering deposition. The films prepared at lower Po had an ilmenite (R3̄) structure, while a corundum (R3̄c) structure was observed in the case of higher Po . The oxidation state of Fe in FeTiO films changed monotonically from Fe to Fe with increasing the Po . The films with the R3̄ symmetry were ferrimagnitic at low temperature, while the nonstoichiometric FeTiO with the R3̄c symmetry were antiferromagnetic at room temperature. © 2003 Elsevier B.V.

Human beings have been using "bengara" (α-Fe O ) as red pigment ever since ancient times. As for Japan, the first artificial "bengara" was manufactured at Fukiya town in 1707, and it was mainly used for red painting of porcelain and other objects for about 300 years. However this "Fukiya bengara" cannot be manufactured anymore because of the environment pollution in spite of eagerness of potters to use it for producing bright yellowish red. At first step, we characterized traditional "Fukiya bengara" and found that α-Al O existed. It is probably due to the formation of Al substituted α-Fe O . Then next step, we prepared red pigment of Fe O -Al O system to investigate the Al substitution effect, by using both solid-state and polymerized complex methods. The red tone color depended on the particle size; the yellowish red pigment had the smallest size. Al substitution seemed to suppress the grain growth of hematite. The red tone color was controllable with the amount of Al substitution. α-(Fe Al ) O prepared at 1000°C for 2 hours presented as bright yellowish red color as that of "Fukiya Bengara". 2 3 2 3 2 3 2 3 2 3 0.9 0.1 2 3

Journal of Materials Research 16 ( 9 ) 2471 - 2474 2001

Well-crystallized Ba Zn Fe O (Zn -Y) films with high c-axis oritentation were successfully formed on Ag substrates at low temperature by the polymeric precursor method. A precursor solution with stoichiometric Ba , Zn , and Fe ions was deposited on the substrates by a dip-coating. The films were then heat-treated at temperatures ranging from 700 to 900°C. The crystallization process of c-axis-oriented Zn -Y films occurred at the considerably low temperature of 750°C, though a small amount of spinel oxides contaminated them. The films had hexagonal grain structures which were developed by increasing the heat-treatment temperature. Magnetization curves of the Zn -Y film heated at 900°C clearly indicated that the film had large in-plane magnetic anisotropy and had small in-plane coercivity. 2 2 12 22 2 2 2 2+ 2+ 3+

Exchange coupling and spin-flip transition of CoFe<inf>2</inf>O<inf>4</inf>/α-Fe<inf>2</inf>O<inf>3</inf> bilayered films

Materials Research Society Symposium - Proceedings 674 2001

CoFe O /α-Fe O (ferrimagnetic/antiferromagnetic) bilayered films were prepared on α-Al O (102) single-crystalline substrates by helicon plasma sputtering. A well-crystallized epitaxial α-Fe O (102) layer was formed on the substrate, while CoFe O grown on α-Fe O (102) was a polycrystalline layer with a (100)-preferred orientation. The α-Fe O (102) films without CoFe O layers clearly showed a spin-flip transition at about 400 K. The spins aligned perpendicular to the film plane at room temperature changed their direction within the film plane above 400 K. However the α-Fe O base layers of CoFe O /α-Fe O bilayered films did not show any spin-flip transition. The CoFe O layer on α-Fe O had a large in-plane magnetic anisotropy, while the spin axis of the α-Fe O (102) base layer was directed perpendicular to the film plane. The magnetization of ferrimagnetic CoFe O layers was coupled perpendicularly to the spin axis of antiferromagnetic α-Fe O layers due to the exchange coupling at the interface between CoFe O and α-Fe O . 2 4 2 3 2 3 2 3 2 4 2 3 2 3 2 4 2 3 2 4 2 3 2 4 2 3 2 3 2 4 2 3 2 4 2 3

Ni-Zn ferrite/SiC sintered composite was prepared as electromagnetic wave absorber through pre-ceramics method and subsequent annealing at 1273 K. Amorphous SiC particles dispersed uniformly in Ni-Zn ferrite matrix and the density of the composites decreased with increasing the amount of SiC particles. The absorption characteristics of the sintered composite were found to depend upon the amount of SiC particles. The matching frequency of the composites shifted toward higher frequency, from about 100 MHz to 1 GHz, with increasing the amount of SiC particles.

The effects of electrochemical removal reaction of lithium from the Li-doped Bi-2212 phase on its structure and superconducting properties have been studied. Lithium was inserted into and removed from Bi₂Sr_1.5Ca_1.5Cu₂O_z through an electrochemical. method at a constant applied potential at room temperature. The original crystal symmetry, tetragonal structure, was maintained and any secondary phase was not formed throughout the electrochemical reactions. Lattice parameter c of the doped samples, Li_xBi₂Sr_1.5Ca_1.5Cu₂O_z, decreased and Tc changed reversibly as the lithium content x decreased, It reveals that the electrochemical reactions were intercalation/deintercalation of the Bi-2212 phase with lithium.

Effects of electrochemical Li-doping to the Pb-substituted Bi-2212 phase on its structural and superconducting properties were studied. Bi Pb Sr Ca Cu O was lithiated through an electrochemical method at constant applied potential at room temperature. In the electrochemically Li-doping samples, the original crystal symmetry, tetragonal structure, was maintained and any secondary phase was not formed. The amount of doped Li for Bi Pb Sr Ca Cu O was much lager than that for Bi Sr Ca Cu O at the same reaction periods. Analysed maximum Li content y for Li Bi Pb Sr Ca Cu O was found to be 0.53, which was remarkably high in comparison with y=0.37 for Li Bi Sr Ca Cu O . The lattice parameters (a,c) of Li Bi Pb Sr Ca Cu O increased continuously in a similar trend to that of Li Bi Sr Ca Cu O . Tc remains almost constant around 85K as the Li content y increased. 1.8 0.2 1.5 1.5 2 z 1.8 0.2 1.5 1.5 2 z 2 1.5 1.5 2 z y 1.8 0.2 1.5 1.5 2 z y 2 1.5 1.5 2 z y 1.8 0.2 1.5 1.5 2 z y 2 1.5 1.5 2 z
