- 論文の詳細を見る
The nature of commensurate and incommensurate helical spin orderings in stackedtriangular XY antiferromagnets CsMnBr_3 and RbMnBr_3 is studied theoretically. The origin of the incommensurate spin structure of RbMnBr_3 is ascribed to an appropriate type of lattice distortion. On the basis of renormalization-group ε and 1/n expansions, it is argued that the lattice commensurability is irrelevant to the criticality of magnetic phase transitions, and both CsMnBr_3 and RbMnBr_3 should belong to the recently identified n=2 chiral universality class.
