比较了Pt/Co/Pt/Y3 Fe 5 O 12(YIG)和Pt/Co/Pt/SiO2多层膜中自旋轨道矩(SOT)诱导的磁化翻转。Pt/Co/Pt/YIG的临界开关电流几乎是Pt/Co/Pt/SiO2的一半。通过谐波测量,我们证明了Pt/Co/Pt/YIG中有效自旋霍尔角的增强。SOT效率的提高归因于Pt/YIG界面处的非平衡邻近效应,该效应抑制了自旋电流反射,增强了Co/Pt界面处的有效自旋积累。该方法可以有效地降低开关电流密度,为SOT的调制提供了另一种途径。
We have compared the spin orbit torque (SOT) induced magnetization switching in Pt/Co/Pt/Y3Fe5O12 (YIG) and Pt/Co/Pt/SiO2 multilayers. The critical switching current in Pt/Co/Pt/YIG is almost half of that in Pt/Co/Pt/SiO2. Through harmonic measurements, we demonstrated the enhancement of the effective spin Hall angle in Pt/Co/Pt/YIG. The increased efficiency of SOT is ascribed to the nonequilibrium proximity effect at the Pt/YIG interface, which suppresses the spin current reflection and enhances the effective spin accumulation at the Co/Pt interface. Our method can effectively reduce the switching current density and provide another way to modulate SOT.
