Abstract

A magnetoresistive random-access memory cell includes a templating layer, including a binary alloy having an alternating layer lattice structure, and a half metallic Heusler multilayer structure including a plurality of layers of two different Heusler compounds, at least one of which is half metallic. The half metallic Heusler multilayer structure is located outward of the templating layer and exhibits perpendicular magnetic anisotropy (PMA). A tunnel barrier is outward of the half metallic Heusler multilayer structure, and a magnetic layer is outward of the tunnel barrier.
