  Magnetic, Transport and Thermal Properties of Itinerant Magnetic U-T(T=Os, Ru and Rh) Systems

  摘要：

  The specific heat, magnetic susceptibility and electrical resistivity of uranium-transition-metal binary U-T(T=Os, Ru and Rh) and pseudo-binary URh1-xTx(T=Os and Ru) systems are presented. These systems are found to be paramagnets except URh. The electronic specific heat coefficient gamma, namely 5f density of states at the Fermi level, increases with the valence d-electron number in order of U-Os, U-Ru and U-Rh systems. URh is perceived to be an itinerant ferromagnet (T(C) = 55 K) because of the small magnetic entropy associated with the ferromagnetic transition and the small spontaneous magnetic moment at 4.2 K. Substitution of Os and Ru for Rh in URh strongly suppresses the ferromagnetic transition, which fact is qualitatively understood within the framework of the itinerant electron theory.
