Anisotropic XY antiferromagnets in a field

Regular Article
Part of the following topical collections:
  1. Recent Advances in Phase Transitions and Critical Phenomena

Abstract

Classical anisotropic XY antiferromagnets in a field on square and simple cubic lattices are studied using mainly Monte Carlo simulations. While in two dimensions the ordered antiferromagnetic and spin-flop phases are observed to be separated by a narrow disordered phase, a line of direct transitions of first order between the two phases and a bicritical point are found in three dimensions. Results are compared to previous findings.
