摘要
A method and system for providing a magnetic substructure usable in a magnetic device, as well as a magnetic element and memory using the substructure are described. The magnetic substructure includes a plurality of ferromagnetic layers and a plurality of nonmagnetic layers. The plurality of ferromagnetic layers are interleaved with the plurality of nonmagnetic layers. The plurality of ferromagnetic layers are immiscible with and chemically stable with respect to the plurality of nonmagnetic layers. The plurality of ferromagnetic layers are substantially free of a magnetically dead layer-producing interaction with the plurality of nonmagnetic layers. Further, the plurality of nonmagnetic layers induce a perpendicular anisotropy in the plurality of ferromagnetic layers. The magnetic substructure is configured to be switchable between a plurality of stable magnetic states when a write current is passed through the magnetic substructure.
