摘要：

The flux-pinning property in a melt-processed Sm-123 bulk superconductor was investigated and the observed irreversibility field was compared with the theoretical model of flux creep and now assuming that the usual condensation energy interaction by 211 particles is dominant in flux pinning. The good agreement suggests that this hypothesis is valid. The pinning mechanism around the peak effect is discussed based on the results on scaling of the pinning force density.
