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.

Physical Phenomena

It is well known that oscillating magnetization induces charge current in a circuit via Faraday’s law of electromagnetic induction. New physical phenomena by which magnetization dynamics can produce charge current have gained considerable interest recently. For example, moving magnetization textures, such as domain walls, generates charge current through the spin-motive force. Here, we examine an entirely different effect, which couples magnetization and electric field at the interface between an ultrathin metallic ferromagnet and dielectric. We show that this coupling can convert magnetic energy into electrical energy. This phenomenon is the Onsager reciprocal of the voltage-controlled magnetic anisotropy effect. The effect provides a previously unexplored probe to measure the magnetization dynamics of nanomagnets.
