【 摘 要 】

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 Cs2CuCl4 by Coldea et al. [Phys. Rev. Lett. 86, 1335 (2001)].
