面外和面内极化自旋电流脉冲联合作用下纳米磁体的超快开关
Ultrafast switching of a nanomagnet by a combined out-of-plane and in-plane polarized spin-current pulse
摘要：
我们报告的自旋阀设备，包括一个平面外的偏振器（ESTA），以快速激发自旋力矩（ST）开关和平面内的偏振器/分析器（IPP）。对于< 200 ps的脉冲，我们观察到可靠的旋进开关，主要是由于ST从OPP。相比于传统的自旋阀，对于给定的电流在短脉冲制度的添加的反相器可以减少开关所需的脉冲宽度的10倍或更多。IPP的影响在更长、更小的脉冲时最明显，但对于短脉冲切换也具有有益的ST结果。
英文摘要：
We report on spin valve devices that incorporate both an out-of-plane polarizer (OPP) to quickly excite spin torque (ST) switching and an in-plane polarizer/analyzer (IPP). For pulses < 200 ps we observe reliable precessional switching due largely to ST from the OPP. Compared to a conventional spin valve, for a given current in the short pulse regime the addition of the OPP can decrease the pulse width necessary for switching by a factor of 10 or more. The influence of the IPP is most obvious at longer, smaller pulses, but also has beneficial ST consequences for short pulse switching.
