The specific heat, magnetic susceptibility and electrical resistivity of uranium-transition-metal binary U-T (T=Os, Ru and Rh) and pseudo-binary URh_<1-x>T_x(T=Os and Ru) systems are presented. These systems are found to be paramagnets except URh. The electronic specific heat coefficient γ, 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 under-stood within the framework of the itinerant electron theory.
