论文摘要
磁性隧道连接是具有微波生成和检测功能的纳米级旋转设备。在这里，我们在磁性隧道连接处使用称为“自旋二极管”的矫正效果来无线检测自动振荡性机制中另一个连接的微波发射。我们表明，可以从每个连接处的独立测量的自动振荡和自旋二极管光谱中重建在接口端测得的校正自旋二极管电压。最后，我们将自动振荡器模型调整为自旋变速器振荡器和自旋变速二极管的情况，我们表明，这可以准确地重现实验观察到的特征。这些结果将对基于微波通信的Spintronic纳米版本设计电路和芯片有用。
Magnetic tunnel junctions are nanoscale spintronic devices with microwave generation and detection capabilities. Here we use the rectification effect called "spin-diode" in a magnetic tunnel junction to wirelessly detect the microwave emission of another junction in the auto-oscillatory regime. We show that the rectified spin-diode voltage measured at the receiving junction end can be reconstructed from the independently measured auto-oscillation and spin diode spectra in each junction. Finally we adapt the auto-oscillator model to the case of spin-torque oscillator and spin-torque diode and we show that accurately reproduces the experimentally observed features. These results will be useful to design circuits and chips based on spintronic nanodevices communicating through microwaves.
