Abstract

The compound U₂Ru₂Sn is known to crystallize in the tetragonal U₃Si₂-type structure and is believed to be a weak paramagnet. We report electrical resistivity studies on this compound which seem to indicate semiconducting behaviour at low temperatures and hence a gap formation in this compound. This is evidenced from a sharp rise in the resistivity seen at low temperatures similar to that observed in the so-called Kondo insulators.
