Abstract
The authors presents results that show sizable current-induced torque and a robust current-induced magnetization switching in weakly spin-orbital coupled Zr based perpendicular magnetized multilayers. Current induced effective torque field changes its sign as the Zr layer thickness varies, indicating the competition of multiple effects. Possible roles of the orbital Hall effect, which generates sizable torque as predicted by theoretical calculation, are discussed.
