Abstract

We report a superconducting phase diagram of the ferromagnetic superconductor UGe2 investigated by AC magnetic susceptibility measurements. In contrast to previous phase diagrams, we found that the superconducting transition temperature and volume fraction show a "M-shaped" structure as a function of pressure. From this observation, we suggest that both of two critical points will play a crucial role in the occurrence of superconductivity in UGe2.
