CRITICAL DOMAIN-STRUCTURES IN PERIODICALLY INHOMOGENEOUS MAGNETIC-FILMS

The static and dynamic properties of the critical domain structures in magnetic films subject to periodic modulation of one of the dependent parameters have been studied. These modulated parameters are the unia xial anisotropy constant, the Curie temperature and the thickness of t he film. The inhomogeneous states of such films are defined and the re spective phase diagrams are constructed. It is shown that uniaxial mag netic films can be a good model for the investigation of phase transit ions with incommensurable structures. Using the results obtained, the conditions for the creation of domain structures with a specified peri od can be predicted and calculated.
