Abstract

The magnetic susceptibility of the title material follows a Curie-Weiss law at high temperatures, and a peak of the susceptibility appears around 4 K associated with remarkable hysteresis below 10 K, which is reminescent of a spin-glass behavior. The temperature dependence of the electrical resistivity is proportional to exp (T^-1/3), which may reveal a two-dimensional variable range hopping.
