Description

We investigated the correlation between structure, oxidation, and magnetic properties of Pt/Co/AlOx heterostructures deposited by magnetron sputtering. We find that the magnetic anisotropy and the spin-orbit torques are both affected by the degree of oxidation of the Co/Al interface. Moreover, we find that oxidation also influences the domain texture and the current-induced domain-wall motion.
