Spin-motive force due to intrinsic magnetic energy difference of a domain wall in a shaped nanostripe

Ieda, Junichi  ; Yamane, Yuta; Oe, Junichiro*; Maekawa, Sadamichi

Recently, it has been revealed that, in magnetic nanostructures, there is a correction to Faraday's law of induction, i.e., the discovery of spin-motive force. Emergence of the spin-motive force involves magnetization dynamics in magnetic nanostructures. Thus far, while the spin-motive force has been demonstrated in experiments, magnetization dynamics in those systems has been driven by applied magnetic fields. Instead, by using a shaped magnetic nanostripe, the generation of spin-motive force without external driving forces has been proposed theoretically. In this work we perform detailed numerical calculations for the proposal.
