Excitation and Dynamics of Domain Walls in Three-Layer Ferromagnetic Structure with Different Parameters of the Magnetic Anisotropy and Exchange

The dynamics of domain walls (DW) in three-layered ferromagnetic was studied. The minimum velocity required for a DW to pass through the spatial modulation region was calculated. The excitation of DW internal oscillation modes and localized magnetic inhomogeneity of breather type was analyzed.
