摘要：

We report on high-field magnetization (M(B)) measurements (B less-than-or-equal-to 35 T) of antiferromagnetic heavy-fermion UPd2Al3 at liquid helium temperatures. The data taken on well-characterized single-crystalline samples reveal a large anisotropy. For a field directed in the hexagonal plane (B parallel-to a-axis) a sharp jump, DELTA-M congruent-to 0.94-mu(B)/U-atom, occurs at B(c) = 18.0 T, while for a field along the hexagonal axis (hard axis) the magnetization is small and almost linear up to 35 T. The jump at B(c) = 18.0 T for B parallel-to a reflects the antiferromagnetic phase boundary.
