UPd2Al3 is a heavy fermion superconductor with Tc ≊ 2 K co-existent with an antiferromagnetically ordered state (TN = 14.5 K. We report the angular dependence of the dHvA frequency, the effective cyclotron mass and the Dingle temperature. A comparison of the experimental results with band-structure calculations is made, revealing that 5f electrons in UPd2Al3 are fairly itinerant. © 1995.

We have observed the de Haas-van Alphen (dHvA) oscillation in both the normal and superconducting mixed states of CeRu2. The dHvA amplitude in the mixed state is extremely reduced for the large cyclotron orbit or the carrier with a large cross-sectional area of the Fermi surface compared to the small one. We have detected three dHvA branches, ranging from 6 × 105 Oe to 2.3 × 107 Oe. The origin of these branches is well explained by the 4f-itinerant band model. © 1995, THE PHYSICAL SOCIETY OF JAPAN.

We reported previously that an anomaly appeared in the specific heat of UPd2Al3.03 in the superconducting state. An anomaly has also been observed in the thermal expansion of a sample, which was cut from the same ingot of UPd2Al3.03 revealing de Haas-van Alphen oscillations. The temperature dependence of the magnetic susceptibility of La0.25U0.75Pd2Al3 shows no peak down to about 5 K contrary to that of UPd2Al3, implying a nonsinglet ground state. © 1994.

dHvA effect on UPd₂Al₃(共著)

UPd2Al3 is a heavy-fermion superconductor with T(c) congruent-to 2 K coexistent with an antiferromagnetically ordered state (T(N) = 14.5 K). We have succeeded in observing the de Haas-van Alphen (dHvA) effect on UPd2Al3 for the first time. In this paper, we report the angular dependence of the dHvA frequency. It is also shown that five branches are observed and effective cyclotron masses are found to range approximately from 10m0 to 32m0. The amplitude of the dHvA signals depends strongly on the magnetic field direction.

We are investigating the delocalization of 5f electrons in uranium compounds by means of the de Haas-van Alphen(dHvA) experiment. The measurements of moderately-heavy fermion compound U3P4 show the complicated angular dependence of the cross-sectional area of the Fermi surface. By contrast, the angular dependence in U3As4 seems rather simple, corresponding to the smaller electronic specific heat coefficient. This result seems to be due to weaker hybridization of 5f electrons with ligands in U3As4 than in U3P4.
