Quasi-one-dimensional anisotropic Heisenberg model in a transverse magnetic field
arXiv:cond-mat/0407203 · doi:10.1134/1.1825110
Abstract
The phase diagram of weakly coupled 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 and the value of interchain interaction in this compound is estimated.
