Observation of hidden altermagnetism in Cs $_{1 - I^´}$ V $_{2}$ Te $_{2}$ O

Guowei Yang, Ruihan Chen, Changchao Liu +25

Altermagnets are characterized by anisotropic band/spin splittings in momentum space, dictated by their spin-space group symmetries. However, the real-space modulations of altermag…
