The possibility of generation of stable self-focusing beams in in-planemagnetized thin magnetic films is considered and theoretical conditions for theexistence of such localized solutions are discussed. It is shown that for thedefinite direction between static magnetizing field and preferential directionof radiation from microwave antenna the problem reduces to the one-dimensionalnonlinear Schroedinger equation. For such angles it is possible to generatestable self-focusing beams. Particular values of beam width and propagationangles versus magnitude of magnetizing field are calculated in order to suggestthe realistic experimental setup for the observation of discovered effect.
