Abstract

Single crystals of superconducting U₆Fe were grown by both thezone-melting method and the Czochralski pulling method.The upper critical field H_c2 was determined from the electrical resistivityin applied magnetic fields, and H_c2 is found to be anisotropic;13.1 T for the field along the [001] directionand 10.4 T for [110]. Anisotropy of H_c2 is well explained by the effective mass model.
