摘要：

The mechanism of magnetic vortex motion in the classical easy-plane antiferromagnet an the vortex gas contribution to the response functions of such magnets are considered for temperatures above the Kosteritz-Thouless transition. Unlike a ferromagnet, gyrotropical properties of such vortices arise only in sufficiently strong transversal magnetic field. Because of that, the magnetic field produces an important effect on the shape and the width of the central peak of the dynamical structure factor of antiferromagnets.
