电流感生自旋轨道力矩(SOT)是实现高速、低功耗自旋电子学器件最有前途的方法之一。然而,SOT驱动磁化反转的机制,特别是类场转矩(FLT)的作用,仍然不清楚。在这里,我们报告所观察到的促进和抑制开关FLT,这取决于FLT和自旋极化的相对方向。研究结果表明,FLT通过影响类阻尼力矩做功来调节开关速度和功耗,并在开关过程中产生两种不同的反向动力学路径。此外,在SOT诱导开关的孕育时间的起源同时澄清。
The current-induced spin-orbit torque (SOT) is one of the most promising ways for high speed and low power spintronics devices. However, the mechanism of SOT driven magnetization reversal, especially the role of the field-like torque (FLT), is still unclear. Here, we report the observed promotion and suppression of switching by FLT, which depends on the relative direction of FLT and spin polarization. Our results reveal that the FLT could modulate the switching speed and power consumption by affecting the work done by the damping-like torque, and leads two different reversal dynamical paths during the switching. Furthermore, the origin of incubation time in SOT induced switching is clarified simultaneously.
