Generation of charge current from magnetization

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 spinmotive force.
