ABSTRACT:
An improved magnetic memory element is provided in which a magnetic sense layer is formed of two ferromagnetic material layers separated by a spacer layer. The two ferromagnetic layers are formed as a synthetic ferrimagnet with stray field coupling and antiferromagnetic exchange coupling across the spacer layer.
