Abstract
The domain walls in ultrathin ferromagnetic films with uniaxial magnet ic anisotropy are investigated theoretically, It is shown that taking account of the magnetodipole and magnetoelastic interactions leads to the appearance of an effective anisotropy with respect to the directio n of the normal to the plane of the wall. The existence of a new type of domain walls-''corner'' walls, at which the magnetization vector is rotated in the plane making a certain angle, which depends on the fil m parameters, with the plane of the domain wall and the static and dyn amic properties of these walls are investigated. The dependence of the limiting velocity of the domain walls on the film thickness is found. (C) 1997 American Institute of Physics.
