MAGNETOELECTRONICS INFORMATION DEVICE HAVING A COMPOUND MAGNETIC FREE LAYER

A magnetoelectronics information device (20) is provided that includes two multi-layer structures (24, 26) and a spacer layer (28) interposed between the two multi-layer structures. Each of the multi-layer structures has two magnetic sublayers (38, 40, and 44, 46) and a spacer layer (42, 48) interpo...

Summary:A magnetoelectronics information device (20) is provided that includes two multi-layer structures (24, 26) and a spacer layer (28) interposed between the two multi-layer structures. Each of the multi-layer structures has two magnetic sublayers (38, 40, and 44, 46) and a spacer layer (42, 48) interposed between the two magnetic sublayers. The spacer layer interposed between the two magnetic sublayers provides an antiferromagnetic exchange coupling that is quantified by a saturation field. The spacer layer interposed between the two multi-layer structures provides a second antiferromagnetic exchange coupling is quantified by another saturation field that is less than the first saturation field.
