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-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.

自旋二极管检测自旋转矩振荡器的微波发射

磁性隧道结是具有微波产生和检测功能的纳米级自旋电子器件。在这里，我们在磁隧道结中使用称为“自旋二极管”的整流效应，以无线方式检测自激振荡中另一个结的微波发射。我们表明，在接收结端处测得的整流自旋二极管电压可以根据每个结中独立测量的自激振荡和自旋二极管光谱重建。最后，我们使自激振荡器模型适应自旋扭矩振荡器和自旋二极管的情况，并表明该模型可以精确地再现实验观察到的特征。这些结果对于设计基于通过微波通信的自旋电子纳米器件的电路和芯片将很有用。
