The FIM layer may be composed of a cobalt-gadolinium (Co—Gd) alloy, cobalt-terbium (Co—Tb) multilayers, or other materials that provide anti-ferromagnetic coupling between two sub-lattices. Negative exchange interaction between the two sub-lattices of the FIM may allow for low current switching. High thermal stability and external magnetic field resistance may also be achieved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High efficiency spin torque switching using a ferrimagnet","description":"In one embodiment, a spin torque device uses a thick (e.g., >1 nm, and preferably >=2-6 nm) ferrimagnet (FIM) layer, instead of a thin (e.g., <1-2 nm) FM layer in the device's stack.
