Abstract
Logic computing in magnetic domain walls is 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 the 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.
