摘要：

Electrical resistivity, magnetic susceptibility and Hall effect were measured on a hexagonal antiferromagnet UCu2Sn. Below T-N = 16 K, the resistivity rho sharply increases along all the a-, b-and c-axis. The anisotropic behavior, rho(b) > rho(a) > rho(c), suggests that the magnetic superzone gap is larger in the c-plane than along the c-axis. However, anisotropy in the magnetization for H parallel to a and H parallel to c is weak even in the antiferromagnetically ordered state. The magnetization curve of a powdered sample exhibits a spin-flop like behavior at 230 kOe. (C) 1998 Elsevier Science B.V. All rights reserved.
