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