Method And System For Providing A Magnetic Junction Using Half Metallic Ferromagnets

摘要

A method and system provide a magnetic junction usable in a magnetic device. The magnetic junction includes a pinned layer, a nonmagnetic spacer layer, and a free layer. The nonmagnetic spacer layer is between the pinned layer and the free layer. The magnetic junction is configured such that the free layer is switchable between a plurality of stable magnetic states when a write current is passed through the magnetic junction. At least one of the free layer and the pinned layer include at least one half-metal.
