Electrical measurements of the polarization in a moving magnetic vortex

Abstract

We propose that the polarization of the moving magnetic vortex core can be detected by the electro-and spin-motive forces acting on the spin-polarized conduction electrons. With parameters appropriate to Permalloy, we have simulated the dynamics of a magnetic vortex core resulting from an applied oscillating magnetic field. We show that the polarization of the moving core can be detected by a simple electrical measurement. (C) 2009 American Institute of Physics.
