Abstract

A brief review of alternative phenomenological approaches to the spin dynamics of antiferromagnets are discussed in virtue of modern interest to ultrafast spin dynamics and it application. Specific properties of antiferromagnets, first of all, the possibility of spin dynamics faster then for ferromagnets are described. Novel types of solitons for anisotropic antiferromagnets are discussed.

Key words: antiferromagnet, soliton, ultrafast spin dynamics.
