Abstract

Single crystals of various uranium-based intermetallics such as UPt₃, UPd₂Al₃, U₆Fe, URu₂Si₂, etc., were grown by the Czochralski pulling method in a tetra-arc furnace. Subsequent annealing treatment by the solid-state electrotransport (SSE) method under ultra-high vacuum is found to be quite effective for compounds UPt₃ and CeRu₂. The residual resistivity ratio (RRR) of CeRu₂ has been improved from 30 to about 300 after the SSE treatment. In the case of UPt₃, the best annealing temperature is about 900°C, where RRR is increased up to 640.
