Material Targets for Scaling All-Spin Logic

Moore's Law has led to device dimensions approaching 10 nm in electronics, as spin-, tunneling- and phase-change-based devices are being explored to continue progress. The authors show a feasible scaling path to lead spin-torque logic to tomorrow's technology. These scaling-parameter relationships and quantitative targets for magnetic materials, spin channels, and interfaces enable spintronics for low-power, high-performance computing, particularly in mobile devices.
