Research Abstract

In order to investigate the relationship between magnetism and superconductivity in f-electron systems, NMR measurements have been performed in several UCoGe samples synthesized with different conditions. We have found that the volume of ferromagnetic phase in the samples increases with increasing their residual resistance ratio (RRR). Since bulk measurements indicate that the volume of superconducting phase also increases with increasing RRR, the NMR result suggests that the ferromagnetic ordering is essential for the occurrence of superconductivity in UCoGe.
