Two models of classic XY antiferromagnets in three dimensions are studied by Monte Carlo simulation: the model on a simple cubic lattice with two extra intralayer exchanges and the model on a stackedtriangular lattice with an extra interlayer exchange. In suggested models, the order parameters are magnetization and two chiral parameters. A transition corresponds to breaking Double-Struck-Capital-Z {sub 2} Circled-Times Double-Struck-Capital-Z {sub 2} Circled-Times SO(2) symmetry. A distinct first order transition is found in both models.
