摘要
We have made detailed investigations of the magnetic and transport properties of the tetragonal compounds UCuP2 and UCuAs2 on single-crystal specimens. The present data indicate that both these compounds are ferromagnets below 75 K and 133 K with spontaneous magnetic moments of 0.98-mu-B and 1.27-mu-B, respectively, and in the magnetically ordered region they exhibit high values of magnetocrystalline anisotropy constants. The electrical resistivity of UCuP2 and UCuAs2 at low temperatures behaves as T2 while, in the temperature range above T(C), the observed negative slope of rho(T) may point to their Kondo lattice behaviour.
