The discrete description of a magnetic medium is used for the investigation of short‐wave spin excitations, which form (under specific conditions) weakly nonlinear dynamical solitons of magnetization. The conditions for the existence of such solitons are obtained and their nonresonant interaction is investigated. We get expressions for the width of the solitons and the shifts of their parameters (frequency and propagation velocity) caused by the nonlinear “self‐action” and by the nonlinear interaction as well.
