Abstract

We present magnetic susceptibility, specific heat, electrical resistivity, magnetoresistance, Hall coefficient, thermal conductivity, thermoelectric power, and ¹¹⁹Sn NMR data for U₂Ru₂Sn. Clear evidence is found for the formation of a gap in the electronic density of states at the Fermi level. Together with the disappearance of the local magnetic moments at low temperatures and the observation of enhanced effective masses this suggests to classify U₂Ru₂Sn as a Kondo insulator.
