Overview of altermagnetism

Altermagnets are compensated weak spin-orbit coupled magnets with characteristic anisotropic patterns of spin splitting in their band structures in momentum space. In this talk, I introduce altermagnetism from the point of view of symmetry. I plan to give some insight into the main features of altermagnets arise from their enhanced magnetic symmetries both phenomenologically and through toy models in both electronic bands and in magnons.
