Easy-plane spin Hall nano-oscillators as spiking neurons for neuromorphic computing

Ferromagnetic nanoconstrictions can serve as integrate-and-fire neurons, communicating via spin-wave pulses analogous to neural spikes. The nanoconstriction geometry leads easy-plane oscillators which manifest phase dynamics damped driven oscillators. authors propose a sample where undergo slips and produce of signals when triggered by small spin torque. They show with the help macrospin modeling micromagnetic simulations that these excite other neurons they possess basic fan-in fan-out capability required for neuromorphic systems.
