自旋转移振荡器与微波电流的锁相耦合效率
Coupling efficiency for phase locking of a spin transfer oscillator to a microwave current
摘要：
实验研究了自旋转移纳米振荡器（STNO）对外部微波信号的锁相行为与STNO本征参数的关系。我们提取的耦合强度从我们的数据使用派生的相位动力学的强制STNO。作为振荡器固有特征（即功率、线宽、电流敏捷性）的函数的锁相耦合强度的预测趋势对于优化相互耦合的STNO阵列中的发射功率至关重要。
英文摘要：
The phase locking behavior of spin transfer nano-oscillators (STNOs) to an external microwave signal is experimentally studied as a function of the STNO intrinsic parameters. We extract the coupling strength from our data using the derived phase dynamics of a forced STNO. The predicted trends on the coupling strength for phase locking as a function of intrinsic features of the oscillators i.e. power, linewidth, agility in current, are central to optimize the emitted power in arrays of mutually coupled STNOs.
