Numerical simulation of the generation of multisoliton type magnetic inhomogeneities in ferromagnets with inhomogeneous parameters

Abstract

The generation and evolution of multisoliton type magnetic inhomogeneities, which appear in two flat layers with the magnetic anisotropy that are different from those in three thick layers after pinning a 180° domain wall, have been investigated theoretically. The structure of the multisoliton type magnetic inhomogeneities have been constructed for the revealed magnetic inhomogeneities, and the ranges of the parameters determining the possibility of their existence have been found.
