摘要

本文报道了基于Damon-Eshbach几何的超薄磁条中自旋波传播的电场控制理论研究。结果表明，利用外加电场控制自旋波沿铁磁体条纹传播的非互易性是可能的。这种效应是由Dzyaloshinskii-Moriya相互作用决定的，这种相互作用是由外部施加的电场效应对磁性离子自旋之间的自旋轨道相互作用施加的。我们的发现为在磁器件中操纵自旋波开辟了一种新的可能性。

Electric Field Control of Spin-wave Propagation in Ferromagnetic Nanostripe

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.
