在 YIG 样品中研究了静水压力（高达 1200 bar）对可逆和不可逆磁化机制的影响。先前针对晶粒内部没有缺陷且未施加压力的样品建立的磁化可逆和不可逆部分之间的关系在压力下仍然有效。磁场参数（例如矫顽力 H c）与磁化参数（例如磁化率）的乘积在压力下的样品中也保持恒定；这一事实允许获得与压力无关的单一曲线。该解释基于磁畴壁形貌随施加压力变化的假设。
The effect of hydrostatic pressure (up to 1200 bar)on the reversible and irreversible magnetization mechanisms has been investigated in YIG samples. The relations between the reversible and irreversible parts of the magnetization, previously established for samples without defect inside the grains and no applied pressure, are shown to remain valid under pressure. The product of field parameters such as coercive force H c by magnetization parameters such as susceptibility remains constant also in samples under pressure; this fact permits a single curve, pressure independent, to be obtained. The interpretation is based on a hypothesis of a variation with the applied pressure of the domain wall topography.
