Degeneracy removal of spin bands in antiferromagnets with non-interconvertible spin motif pair featured image

Degeneracy removal of spin bands in antiferromagnets with non-interconvertible spin motif pair

Establishes the *non-interconvertible spin motif pair* symmetry criterion as the operational definition for these candidates — a rule that can be evaluated by inspection or by …

Strong influence of nonmagnetic ligands on the momentum-dependent spin splitting in antiferromagnets

Shows that non-magnetic ligand chemistry — not just the transition-metal sub-lattice — controls the magnitude of the non-relativistic spin splitting, giving a chemical knob for …
