Modeling circuits with spins and magnets for all-spin logic

This talk will summarize our work in the last three years exploring the possibility of spin-magnet circuits that utilize two key recent advances, namely (1) spin valve (SV) devices demonstrating spin injection into metals and semiconductors from magnetic contacts and (2) spin transfer torque (STT) devices demonstrating the switching of magnets by the injected spins. Utilizing an experimentally benchmarked model describing these phenomena we have shown the possibility of Boolean all-spin logic (ASL) circuits with intrinsic directionality or with directionality enforced through STT based Bennett clocking. We also discuss probabilistic ASL circuits and summarize the modeling framework that we have developed for the analysis of generic spin-magnet circuits.
