摘要
磁空间群相对于以往的空间群 ,在对物理图像的描述上更准确、更深刻。如它可在考虑晶体对称性的同时 ,也考虑到自旋磁矩的作用 ,因而它的C G系数更加重要。本文利用本征函数法 ,计算了面心立方结构O8h 磁空间群的C G系数 ,以及波矢选择规则和C G序列。
Magnetism space group is more accurate in explaining physics picture than traditional space group.For example,it can reflect spin as well as the symmetries of the crystal system,so the Clebsch-Gorden(C-G) coefficients of magnetism space group play a more important role.In this paper,the eigenfunction method established by Chen Jingquan is used to compute the C-G coefficients for the structure O 8 h magnetism space group,wavevector selection rule and C-G series.
