Long-range vortex domain wall displacement induced by an alternating current: Micromagnetic simulations
2008 (English)In: Physical Review B. Condensed Matter and Materials Physics, ISSN 1098-0121, E-ISSN 1550-235X, Vol. 78, no 1, 012413- p.Article in journal (Refereed) Published
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.
