Abstract
The phase diagram of weakly coupled XXZ chains in a transverse magnetic field is studied using the mean-field approximation for the interchain coupling and known exact results for an effective one-dimensional model. The results are applied to the quasi-one-dimensional antiferromagnet Cs2CoCl4, and the value of interchain interaction in this compound is estimated.
