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 non-magnetic substrate material. A pair of electrical drive lines associated with a post element permit coincident current selection of the post element to reverse the direction of magnetization of the post element. This reversal is enhanced by one of the drive lines being configured to a slope portion of the post element so that this drive line is oriented to require a minimum field to reverse the magnetization direction of the post element.
