Spin wave theory for antiferromagnetic XXZ spin model on a triangle lattice in the presence of an external magnetic field
arXiv:cond-mat/0210222 · doi:10.1103/PhysRevB.67.144427
Abstract
Spin wave theory is applied to a quantum antiferromagnetic XXZ model on a triangle lattice in the presence of an in-plane magnetic field. The effect of the field is found to enhance the quantum fluctuation and to reduce the sublattice magnetization at the intermediate field strength in the anisotropic case. The possible implication to the field driven quantum phase transition from a spin solid to a spin liquid is discussed.
