By means of the analysis of crystalline structure and verification of experimental data, a hypothesis is proposed: under the action of applied magneic fields, the directional ordering of the atomic pairs will produce a induced magnetic anisotropy and disappear the structure of crystals.
通过对晶体结构分析和实验验证,提出了一种假设:在外磁场作用下,产生了原子对的方向有序化,导致感生磁各向异性,并使晶体织构消失。

性质:无序结构和有序结构的相互转化。通常高温有利于向无序相转化,低温则有利于有序相;骤冷利于无序而缓冷利于有序。有序-无序转化会影响物质的物理性质和化学性质,例如随着有序的进行,合金的硬度会升高,而电阻、塑性等会降低。某些铁电体在居里温度以上存在无序排列的偶极子,在居里温度以下偶极子自发定向排列,并引起结构上微小畸变而产生自发极化。磷酸二氢钾、酒石酸钾钠,硫酸三甘钛等铁电体具有这类相变,因此也可称他们为有序-无序铁电体。相变温度对实际使用有明显影响。
