Ground states of a frustrated spin-1/2 antifferomagnet: Cs_2CuCl_4 in a magnetic field

M. Y. Veillette, J. T. Chalker, R. Coldea

We present detailed calculations of the magnetic ground state properties of Cs${}_2$CuCl${}_4$ in an applied magnetic field, and compare our results with recent experiments. The materi…
