Abstract

UPd₂Al₃ is a heavy-fermion superconductor with T_c ≅ 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.
