  • Title: Prediction of giant spin motive force due to Rashba spin-orbit coupling.
    Author: Kim KW, Moon JH, Lee KJ, Lee HW.
    Journal: Phys Rev Lett; 2012 May 25; 108(21):217202. PubMed ID: 23003294.
    Abstract:
    Magnetization dynamics in a ferromagnet can induce a spin-dependent electric field through a spin motive force. Spin current generated by the spin-dependent electric field can in turn modify the magnetization dynamics through spin-transfer torque. While this feedback effect is usually weak and thus ignored, we predict that in Rashba spin-orbit coupling systems with a large Rashba parameter α(R), the coupling generates the spin-dependent electric field [±(α(R)m(e)/eħ)(z[over ^]×∂m/∂t)], which can be large enough to modify the magnetization dynamics significantly. This effect should be relevant for device applications based on ultrathin magnetic layers with strong Rashba spin-orbit coupling.
