Times Cited Count：9 Percentile：52.54(Physics, Multidisciplinary)Pressure phase diagram of the antiferromagnet UIn3 was constructed from the electrical resistivity measurement under high pressures up to 9 GPa. Neel temperature increases monotonically with increasing pressure from 88 K at ambient pressure to 127 K at 9 GPa. We observed an additional resistive anomaly at 21 K under 1.4 GPa. This anomaly brings about an increase of the residual resistivity. The transition temperature decreases gradually with increasing pressure and disappears around 8 GPa.

In the previous studies for the pressure-induced structural changes in liquids of tetrahedrally bonded materials, the followings are elucidated. (1) With increasing pressure, the anisotropy in local structures becomes smaller and liquids approach simple liquid metals. (2) The pressure-induced changes become less prominent and the liquids take a unique structure which does not change by compression. (3) As a result, the liquid preserves anisotropy in the local structure at pressures where the crystalline counterpart loses the anisotropy. In our previous studies, the pressure-induced changes were analyzed with the distorted crystalline model. However, this model assumes the existence of the crystalline-type local structure. In the present study, we analyzed it with a RMC method, which does not involve such assumption. Based on the results, we discuss the high-pressure evolution of the local structures in the liquids.
