Electric Field Control of Spin-wave Propagation in Ferromagnetic Nanostripe

Abstract

We report theoretical investigation of electric field control of spin-wave propagation in ultrathin magnetic stripe for the Damon-Eshbach geometry. It is shown, that is possible to control nonreciprocity of spin wave propagation along stripe of ferromagnet by external electric field. This effect is determined by the Dzyaloshinskii-Moriya interaction that is enforced in the system by an externally applied electrical field effect on spin orbital interaction between spins of magnetic ions. Our findings open a new possibility for spin wave manipulation in magnonic devices.
