Abstract
An electrical device structure including a magnetic tunnel junction structure having a first tunnel junction dielectric layer positioned between a free magnetization layer and a fixed magnetization layer. A magnetization enhancement stack present on the magnetic tunnel junction structure. The magnetization enhancement stack includes a second tunnel junction layer that is in contact with the free magnetization layer of the magnetic tunnel junction structure, a metal contact layer present on the second tunnel junction layer, and a metal electrode layer present on the metal contact layer. A metallic ring on a sidewall of the magnetic enhancement stack, wherein a base of the metallic ring may be in contact with the free magnetization layer of the magnetic tunnel junction structure.
