Abstract
A model of a ferramagnet with nonuniform dissipation is introduced for the Landau-Lifshitz equations. It is shown that in this model a ferro magnet can be regarded as an oscillating active medium where the forma tion of autowave structures - spin autowaves, pacemakers, and spiral w aves - is possible. Their wave characteristics, expressed in terms of the parameters of the medium, are found for a special case. (C) 1997 A merican Institute of Physics.
