Abstract
A magnetic memory cell and method of manufacturing thereof, wherein the angle between the shape anisotropy axis and the intrinsic anisotropy axis of the magnetic material layer is optimized to minimize fluctuations in the switching field. The angle between shape anisotropy axis and intrinsic anisotropy axis is preferably between 45 and less than 90 degrees. Magnetic layers may be used having increased thickness, resulting in increased activation energy. Magnetic memory cells may be manufactured that are more stable for long term storage and have improved write margins.
