Antiferromagnetic metals have been attracting attention for future spintronics devices since the recent discovery of electric-current-induced antiferromagnetic domain switching. Here, the authors present a general symmetry analysis of current-induced switching of antiferromagnets in a group-theoretical way. The criterion for switchable antiferromagnets leads to the identification of a dozen of antiferromagnets as candidate materials and reveals a link with the toroidal moment in such materials. The link suggests possible functionalities of the switchable antiferromagnets and paves the way for perfect writing and reading of antiferromagnetic domains.
