A classification of magnetic point groups is presented which gives an answer to the question: which magnetic groups can describe a given magnetic mode? There are 32 categories of magnetic point groups which describe 64 unique magnetic modes: 16 with a ferromagnetic component and 48 without. This classification focused on magnetic modes is helpful for finding the magnetic space group which can describe the magnetic symmetry of the material.
提出了一种点群的分类方法,它回答了这样一个问题:哪些磁点群可以描述给定的磁模式?有 32 类磁点群描述了 64 种独特的磁模式:16 种具有铁磁分量,48 种没有。这种侧重于磁模式的分类对于寻找可以描述材料磁对称性的磁空间群很有帮助。
