Such a device may include two or more magnetic stacks with an easy-in-plane ferromagnetic film sandwiched between oppositely magnetically oriented perpendicular magnetization anisotropy (PMA) ferromagnets. Each stack includes two non-magnetic layers separating the easy-plane ferromagnetic film from the PMA layers. Charge current flow through one of these stacks controls the current-voltage negative differential resistance characteristics of the second stack through collective magnetic interactions. This can be exploited in a variety of digital logic gates consuming less energy than conventional CMOS integrated circuits. Furthermore, the easy-in-plane magnetic films may be subdivided into regions coupled through exchange interactions and the in-plane fixed magnetic layers in the input magnetic stacks can be used in non-volatile logic and memory."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transistor that employs collective magnetic effects thereby providing improved energy efficiency","description":"A device or class of devices that provides a mechanism for controlling charge current flow in transistors that employs collective magnetic effects to overcome voltage limitations associated with singl","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9825218","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.
