Extended Data Fig. 3: Relationship between the FM/AFM dichotomy and further classification schemes, including altermagnetism and SOM.
From: Symmetry classification of magnetic orders using oriented spin space groups
The FM class can be further classified into FM (M ≠ 0), ferrimagnetism (FiM, M ≠ 0) and compensated FiM (M = 0). The AFM class can also be further classified on the basis of different properties as criteria. Therefore, distinct classes of corresponding classification do not necessarily encompass each other. ‘Non-SS pure AFM’ stands for AFM without either spin splitting or SOC-induced magnetization.
