The magnetic junction includes a free layer, a pinned layer and nonmagnetic spacer layer between the free and pinned layers. The free layer is switchable between stable magnetic states when a write current is passed through the magnetic junction. The write current generates joule heating such that the free layer has a switching temperature greater than room temperature. The free layer includes a multilayer that is temperature sensitive and has at least one bilayer. Each bilayer includes first and second layers. The first layer includes an alloy of a magnetic transition metal and a rare earth. The second layer includes a magnetic layer. The multilayer has a room temperature coercivity and a switching temperature coercivity. The switching temperature coercivity is not more than one-half of the room temperature coercivity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for providing magnetic junctions using thermally assisted spin transfer torque switching","description":"A magnetic junction usable in a magnetic device and a method for providing the magnetic junction are described.
