摘要：
Simple examples of lattice models of integrable quantum magnetics with competing interactions are studied. In the definite range of exchange integrals, these models exhibit a magnetic ordering incommensurate with a lattice. We prove that the incommensurability is closely related with the phenomenon of level crossing. Some universal features of the incommensurate phases are described. © 1990 The American Physical Society.
