摘要

The temperature dependence of the thermal expansion coefficient α has been measured in URu_2Si_2 under uniaxial pressure σ along the [100] and [110] directions up to ～0.6 GPa. For both cases, the hidden-order phase transition temperature T_0 increases with increasing uniaxial pressure. An anomaly Δα of the thermal expansion coefficient at T_0 appears to be enhanced under a small uniaxial pressure (＜0.03 GPa). An antiferromagnetically ordered phase appears at T_x above the critical pressure σ_x ～ 0.25 GPa for uniaxial pressure along the [100] direction, whereas no antiferromagnetic transition is detected up to ～0.6 GPa for uniaxial pressure along the [110] direction, indicating that the critical pressure is beyond ～0.6 GPa for the [110] case. In the previously reported hydrostatic case, an antiferromagnetic phase transition appears above the critical pressure P_x ～ 0.5 GPa. The difference in critical pressure between σ_x and P_x can be understood in terms of the pressure dependence of the U-U distance in the basal (001) plane.
