One-dimensional dynamics of the domain boundary in a multilayer ferromagnetic structure

Using the example of a seven-layer ferromagnetic structure with three thin (nanoscale) and four wide magnetic layers, possible scenarios domain boundary dynamics in multilayer ferromagnet are considered. Significant differences were found presence layers increased decreased values anisotropy constant. A diagram is constructed depending on initial velocity its movement distance between layers. The critical separating into two regions qualitatively different behavior system revealed. Keywords: wall, dynamics, ferromagnet, nanostructure, spatial modulation anisotropy.
