During operation, an existing direction of magnetization of the free magnet is changed to a new direction of magnetization, by a spin current generated by transfer of heat between at least the spacer and the pinned magnet. Thereafter, the new direction of magnetization of the free magnet is sensed. Many such structures are fabricated to have an easy axis of magnetic anisotropy in the free magnet, to implement memories that write data by transferring heat. Several such structures are fabricated to have an easy plane of magnetic anisotropy in the free magnet, to implement oscillators that generate an oscillating signal, on transfer of heat."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Creating spin-transfer torque in oscillators and memories","description":"A structure includes an electrically conductive material possessing spontaneous magnetization (“free magnet”) not in contact with an electrically resistive material possessing spontaneous magnetizatio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8467235","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
