摘要

We obtained an oscillatory RKKY nature within the Pt/Co/NiO/Co/Pt stack by changing NiO thickness. This allowed us to develop spin-orbit torque (SOT) devices featuring synthetic antiferromagnetic (AFM) and ferromagnetic (FM) couplings. Field-free switching with perpendicular magnetic anisotropy was achievable in AFM- and FM-coupled devices. Nevertheless, a lower switching current density but a larger switching percentage were obtained in the AFM compared to the FM case. The interlayer exchange coupling strength of the NiO was estimated to be close to that of metallic Wand Ta as a spacer material.
