Abstract
A magnetic domain device has at least one post element formed from a material that exhibits magnetic domain characteristics and that is positioned on a nonmagnetic substrate material. A pair of electrical drive lines associated with a post element permit coincident current selection of the post element to nucleate a magnetic domain reversal, and an additional current introduced into an adjacent drive line establishes an additive magnetic field to assist the propagation of a domain wall associated with the nucleated magnetic domain reversal so that the direction of magnetization of the post element is reversed.
