我们研究了沿[001]和[111]方向施加磁场时的电阻率。相应的(C)磁有序相在压力作用下明显稳定,在低压下观察到另一个额外的相(记为相A)。这一相出现在环境压力下不相称的磁序形成的转变温度以上。磁相图在压力下发生了剧烈的变化。短程相互作用,强烈依赖于Pr-Pr距离,可能在不同相的相对稳定性中起主导作用。
We have studied the electrical resistivity ofunder pressure up to, with magnetic fields applied along the [001] and [111] directions. The commensurate (C) magnetic ordered phase is significantly stabilized by pressure, and another extra phase (denoted phase A) is observed under a low pressure of. This phase appears above the transition temperatureat which the incommensurate magnetic order sets in at the ambient pressure. The magnetic phase diagram forchanges drastically under pressure. Short-range interactions, which are strongly dependent on the Pr-Pr distances, are likely to play a dominant role in the relative stability of the different phases.
