对压力诱导超导体uge2进行了P压下的直流磁化和中子散射实验。我们发现在铁磁态的特征温度T *处磁矩增强，其中T *小于居里温度T C。在P C * =1.20 GPa附近，T *变为0 K，超导转变温度T SC达到最大值。随压力增大而减小的特征温度T *也取决于磁场。
We performed DC-magnetization and neutron scattering experiments under pressure P for a pressure-induced superconductor UGe 2 . We found that the magnetic moment is enhanced at a characteristic temperature T * in the ferromagnetic state, where T * is smaller than a Curie temperature T C . This enhancement becomes remarkable in the vicinity of P C * =1.20 GPa, where T * becomes 0 K and the superconducting transition temperature T SC shows a maximum. The characteristic temperature T * , which decreases with increasing pressure, also depends on the magnetic field.
