To address thermal stability issues for spintronic devices with a reduced size, we investigate spin-orbit torque in Co/Pt multilayers strong perpendicular magnetic anisotropy. Note that the arises from global imbalance of spin currents top and bottom interfaces each Co layer. By inserting Ta or Cu layers to strengthen top-down asymmetry, efficiency can be greatly modified without compromised Above all, builds up as number increases, realizing robust high spin-orbit-torque simultaneously structure.
