Abstract
Nonlinear dynamics of an antiferromagnet in continuum approximation on the basis of the Heisenberg Hamiltonian for two sublattices with biqu adratic exchange interaction in each sublattice and single ion anisotr opy is considered. Exact particular solution, describing the stationar y kink movement, including the region upsilon greater-than-or-equal-to c, is found.
