Abstract

The results of measurements of electrical resistivity ρ, magnetic susceptibility χ, magnetization M and specific heat C are reported on single-crystalline samples of CePdAs and CePdSb. As for CePdAs, ρ(T) perpendicular to the c-axis behaves like a metal and a sharp drop appears around 4 K corresponding to the magnetic transition. But ρ(T) parallel to the c-axis shows a maximum at about 10 K and semiconducting behavior at high temperature. ρ(T) perpendicular to the c-axis on CePdSb shows the same metallic behavior as in the case of CePdAs. The strong aniosotropy in ρ(T) suggests that CePdAs and CePdSb are better characterized as quasi-two-dimensional electrical conductors. This anisotropy is also manifested in χ and M. χ(T) and M(H) along the c-axis of CePdAs and CePdSb exhibits antiferromagnetic ordering at 4 and 17 K, respectively. But χ(T) along the a-axis increases, with decreasing temperature following Curie-Weiss-like behavior of a ferromagnet.
