Topologically Protected Surface Altermagnetism on Antiferromagnets
Valentin Leeb, Peru d'Ornellas, Fernando de Juan +1
Altermagnetism (AM) and its associated spin-transport phenomena are typically linked to spin-split electronic band structures in bulk materials. However, the crystal surface has a…

Collinear -wave magnetism and hidden orbital ferrimagnetism
Valentin Leeb, Johannes Knolle
In the absence of spin-orbit coupling, collinear magnets are classified as even-wave magnets, i.e., either ferro-, antiferro-, or altermagnets. It is based on the belief that colli…
