Abstract
The propagation of nonlinear dipole spin waves in a film consisting of a two-sublattice, uniaxial, antiferromagnetic material has been inves tigated. The external magnetic field is assumed to be parallel to the anisotropy axis of the antiferromagnetic film and is directed parallel , or perpendicular, to the film surface. The existence of envelope sol itons of spin waves is predicted and conditions for their creation are discussed.
