Abstract

The tetragonal compound U₂Ru₂Sn shares several properties with the strongly correlated semimetal CeNiSn. Here we present, for the first time, measurements of magnetic, thermal, and electrical transport properties of single-crystalline samples and compare them to results on polycrystals. The specific heat and the magnetic susceptibility provide evidence for the opening of an energy gap of approximately 150-160 K. Both the magnetic susceptibility and the electrical resistivity are anisotropic. The c-axis is the easy magnetic axis along which the resistivity is 'metal-like'. The resistivity along the a-axis is 'semiconductor-like'.
