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. Results are applied to the
quasi-one-dimensional antiferromagnet Cs2CoCl4 and the
value of interchain interaction in this compound is estimated.
