Solitons in isotropic antiferromagnets: beyond a sigma model

Анотація:

Isotropic antiferromagnets shows a reach variety of magnetic solitons with nontrivial static and dynamic properties. One-dimensional soliton elementary excitations have a periodic dispersion law. For two-dimensional case, planar antiferromagnetic vortices having nonsingular macroscopic core with the saturated magnetic moment are present. The dynamic properties of these planar antiferromagnetic vorteces are characterized by presence of a gyroforce.
