Динамические режимы в тонких пермаллоевых магнитных плёнках различных толщин в постоянном магнитном поле

Abstract

This work deals with model of permalloy magnetic film in constant magnetic film. Micromagnetic simulation has shown that with change of film thickness and value of magnetic field different dynamic regimes existed depending on starting conditions. Between most interesting ones are movement of Neel walls with deformations for extremely thin films and cross-tie walls movement with periodical born and annihilation of 3D- topological structures for more thick films.
