Abstract

Altermagnets are an unconventional type of magnetic state with various appealing properties, both from the fundamental and applied physics perspectives. By investigating the impact of spin-orbit coupling on these states, this work reveals that all altermagnets are intrinsically noncollinear and that their Zeeman splittings possess symmetry-protected nodal lines. These features endow altermagnets with a remarkable resilience against external magnetic fields.
