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.
