Abstract

The current-driven domain wall motion was investigated on permalloy nanowires with different dimensions by micromagnetic simulations. The critical current density increased with the reduction in both the width and thickness of nanowires because of the enhanced hard-axis anisotropy. At a thickness of 5 nm, the critical current density decreased with the reduction of the nanowire width because of the reduced domain wall width.
