Abstract

The domain walls in a sandwichlike structure (an ultrathin magnetic layer is situated between two nonmagnetic plates) are investigated theoretically. Taking account of the magnetodipole and magnetoelastic interaction is shown to lead to the appearance of an effective anisotropy with respect to the direction of the normal to the wall plane. A type of domain wall, “angular” walls, at which the magnetization vector rotates in the plane making a certain angle with the wall plane, is proved to exist at a sufficiently small magnetic layer thickness. The static and dynamic properties of these walls are investigated, in particular, the dependence of the limiting velocity of the domain wall on the magnetic film thickness is found.
