dc.description.abstract | Using micromagnetic simulation, we investigate the effect of enhanced damping induced by spin-motive force on the vortex dynamics. It is found that the enhanced damping does not affect the resonance frequency of gyrotropic motion. However, it changes the gyration radius, the velocity of a vortex core, and the dynamics of core reversal. During the gyrotropic motion, the additional damping goes up to three times larger than a typical value of the intrinsic damping. Moreover, in the case of core reversal, the additional damping becomes 10 times larger than the intrinsic damping. For vortex dynamics, the enhanced damping due to spin-motive is non-negligible and thus should be considered to understand experimental results. (C) 2012 American Institute of Physics.
