Static and dynamic properties of an isolated strip domain in a thin ferromagnetic film

A perturbation theory is developed for the integrodifferential Landau-Lifshits equation that describes the state of 2π-domain walls in ferromagnetic films. The static and dynamic parameters of a 2π-domain wall are determined, taking into account its micromagnetic structure. The limits of applicability of geometric domain wall models are indicated. Fiz.
