Abstract

We have measured the magnetic susceptibility, specific heat, NMR, electrical resistivity, magnetoresistance, Hall effect, thermoelectric power, and thermal conductivity of polycrystalline U₂Ru₂Sn. Some of these properties are compared to those of Th₂Ru₂Sn. The experimental data indicate the formation of a narrow energy gap of approximately k_B X 160 K in U₂Ru₂Sn. Similarities to the behavior of heavy-fermion semiconductors (Kondo insulators) are observed, in particular to CeNiSn. Thus, we believe that U₂Ru₂Sn may be classified as a heavy-fermion semiconductor.
