“Optoelectronic domain-wall motion for logic computing” is out in APL
“Optoelectronic domain-wall motion for logic computing” was published in Applied Physics Letters (Vol.116, Issue 25)
Logic computing in magnetic domain walls has been investigated using the interplay of all-optical helicity-dependent switching and current-induced spin-orbit torque switching. By simultaneously controlling current and laser pulses, logic functions of AND, OR, NAND and NOR are experimentally demonstrated through anomalous Hall effect and verified by micromagnetic simulations. The optoelectronic domain-wall motion is energy-efficient compared to the traditional all-current approach and provides another degree of freedom for the realization of logic applications.
