Abstract:
1. An assembly, comprising: a magnetic memory element supported over a substrate; the magnetic memory element comprising three materials; the three materials being, in ascending order from the substrate, a first material corresponding to a soft magnetic material, a second material corresponding to a non-magnetic material, and a third material corresponding to another soft magnetic material; the magnetic memory element having a vertical sidewall that extends along the first, second and third materials; the first, second and third materials being coplanar along said vertical sidewall; the vertical sidewall extending entirely around the magnetic memory element, and thus defining a lateral periphery of the magnetic memory element; and a magnetic barrier material extending substantially around the lateral periphery of the magnetic memory element; the magnetic barrier material being laterally offset from the memory element by at least one electrically insulative material; the magnetic barrier material vertically overlapping two of the three materials of the magnetic memory element.
