Abstract

- A magnetic vortex domain wall, confined in a Permalloy nanowire with periodically varying width, is brought to resonance and long-range motion by means of a spin-polarized alternating current in micromagnetical simulations. The long-range direction of motion is found to be dependent on the vortex chirality but independent of the vortex polarity. Compared to the case where a direct current is used to move the vortex domain wall, the threshold current density for long-range motion is significantly reduced.
