摘要

交替磁体是具有完全补偿自旋和破缺PT （PT：宇称乘以时间反转）对称性（即自旋分裂带）的磁态。我们根据P和t的破缺对三种交替磁体进行了分类，强交替磁体具有不存在自旋轨道耦合（SOC）的自旋分裂带，而弱交替磁体只有非零SOC的自旋分裂带。这些强弱交替磁体可以从对称自旋旋转操作的总数中识别出来。

Altermagnetism classification

Altermagnets are magnetic states with fully compensated spins and broken PT (PT: parity times time reversal) symmetry (i.e., spin-split bands). We classify three kinds of altermagnets in terms of broken P and T. Furthermore, strong altermagnets have spin-split bands without spin-orbit coupling (SOC), and weak altermagnets has spin-split bands only with non-zero SOC. These strong vs. weak altermagnets can be identified from the total number of symmetric spin rotation operations.
