Author(s): Rui Chen, Bin Zhou, and Dong-Hui Xu Altermagnets are a recently discovered class of magnetic materials that combine a collinear, zero-magnetization spin structure, characteristic of antiferromagnets, with spin-split electronic bands, a hallmark of ferromagnets. This unique behavior arises from the breaking of combined time-reversal an… [Phys. Rev. Lett. 137, 046705] Published Wed Jul 22, 2026
