自旋扭矩（ST）驱动的磁化动力学已被研究的自旋阀结构，包括一个平面内（IP）的自由层和两个固定的偏振器[磁化IP和平面外（OP）]。三个不同的动态，包括没有开关，开关，和周期性振荡被确定在ST参数所支配的相图。ST的强度，能够切换自由层已被解析预测和支持的模拟，表明源自OP偏振器的扭矩应该是远远小于从IP偏振器。由双偏振器驱动的自由层可以比由单个IP偏振器驱动的自由层快10倍。
Spin-torque (ST) driven magnetization dynamics have been investigated in a spin-valve structure that consists of an in-plane (IP) free layer and two fixed polarizers [magnetized IP and out-of-plane (OP)]. Three distinct dynamics including no switching, switching, and periodic oscillation are identified in a phase diagram governed by the ST parameters. The ST strengths which are able to switch the free layer have been analytically predicted and supported by simulations, showing that the torque originated from the OP polarizer should be much smaller than that from the IP polarizer. The free layer driven by the dual polarizers could switch 10 times faster than that by a single IP polarizer.
