Abstract
Effective dynamic equations describing weakly non-linear exchange-magn etostatic excitations are derived for the antiferromagnetic film with an 'easy-plane' anisotropy. The existence of 'algebraic' solitons has been predicted. The conditions for the excitation of soliton states ar e investigated for various values of magnetic field perpendicular to t he surface of the film and film thickness. The soliton relaxation is d iscussed.
