We have examined the intrinsic surface physical property of a CrO 2 thin film by means of surface sensitive photoemission spectroscopy. Epitaxial thin film of CrO 2(100) has been grown on TiO 2(100) by a closed chemical vapor deposition method using a Cr 8O 21 precursor. Low-energy electron diffraction (LEED) observations find that epitaxial growth of rutile-phase CrO 2 occurs to the top monolayer of the film. Surface sensitive x-ray photoemission spectroscopy (XPS) measurements show a finite intensity in the region of the Fermi energy. The result evidences that the physical nature of near topmost layer of CrO 2 thin film is metallic. Progress of understanding of the surface physical property of CrO 2 thin film helps not only perform a reliable photoemission study to understand the physics of ferromagnetic metal in CrO 2, but also develop the CrO 2-based devices using a half-metallic nature for spintronics applications. © 2012 Materials Research Society.

We have prepared a CrO2 thin film by chemical vapor deposition from a Cr8O21 precursor and studied the bulk and surface physical properties. The CrO2 thin film is grown on TiO 2(100) substrate by heating precursor and TiO2 (100) substrate together in a sealed quartz tube. The prepared film is found from x-ray diffraction analysis to be an (100)-oriented single phase. The magnetization and resistivity measurements indicate that the film is a ferromagnetic metal with a Curie temperature of about 400 K. Cr 3s core-level and valence band photoelectron spectroscopy spectra reveal the presence of a metallic CrO2 in the surface region of the film. Our work indicates that preparation from a Cr8O21 precursor in a closed system is promising for obtaining a CrO2 thin film with the metallic surface. © 2011 Materials Research Society.
