Description

Pressure-induced superconductivity is found in UIr without inversion symmetry. The pressure-temperature phase diagram has been investigated by means of electrical resistivity and magnetization. The phase diagram consists of two ferromagnetic phases. The ferromagnetic phase FM1 with TC1∼46K at ambient pressure disappears around 1.7GPa. With further increase of pressure, the phase (FM2) with small ferromagnetic moment appears in the pressure range of PC1<P<2.6GPa. The superconducting phase exists near the disappearance point of the FM2 phase, indicating that the superconductivity is associated with the ferromagnetic critical fluctuation around PC2
