Antiferromagnetic Heisenberg model on anisotropic triangular lattice in the presence of magnetic field

Abstract

We use Schwinger boson mean field theory to study the antiferromagnetic spin-1/2 Heisenberg model on an anisotropic triangular lattice in the presence of a uniform external magnetic field. We calculate the field dependence of the spin incommensurability in the ordered spin spiral phase, and compare the results to the recent experiments in Cs${}_2$CuCl${}_4$ by Coldea et al. (Phys. Rev. Lett. 86, 1335 (2001)).
