Anisotropy in a Heavy Fermion Superconductor: UPd₂Al₃

We report on the anisotropy of magnetization, electrical resistivity and upper critical magnetic fields (H_C2) of UPd₂Al₃. The magnetization curve in the antiferromagnetically ordered state shows large anisotropy, indicating that the sublattice moments lie in the basal hexagonal plane. The value of -(dH_C2/dT) at T_C is estimated to be about 36 (kOe/K) for the magnetic field parallel and perpendicular to the hexagonal c-axis, and the upper critical field seems to be rather isotropic.
