Abstract

A magnetic memory element that has a stress-induced magnetic anisotropy. The memory element has a ferromagnetic free layer having a switchable magnetization orientation switchable, a ferromagnetic reference layer having a pinned magnetization orientation, and a non-magnetic spacer layer therebetween. The free layer may be circular, essentially circular or nearly circular.
