arXiv:cond-mat/9211005 · doi:10.1103/PhysRevB.47.8613

Abstract

A graded H.P,realization of the SU(2|1) algebra is proposed.A spin-wave theory with a condition that the sublattice magnetization is zero is discussed.The long-range spiral phase is investigated.The spin-spin correlator is calculated.
