Different facets of unconventional magnetism

Nature Physics (2025)Cite this article

Subjects

Recent advances in classifying magnets according to spin-group symmetry have expanded the possibilities of unconventional magnetism. Unconventional magnets — such as collinear spin-split antiferromagnets, also known as altermagnets, noncollinear spin-split antiferromagnets and anomalous-Hall antiferromagnets — combine the advantages of ferromagnetism and antiferromagnetism.
