摘要

分析了两个弱耦合自旋力矩纳米振荡器(STNOs)系统的微波动力学特性。结果表明，该系统的同步判据为复阶参数模量随时间的微小变化。利用该准则对具有随机特征频率(高斯分布)和初始相位(矩形分布)的STNOs的微波同步进行了数值研究。

Microwave phase-locking of two weakly-coupled spin-torque nano-oscillators with random eigen parameters

Microwave dynamics of the system of two weakly-coupled spin-torque nano-oscillators (STNOs) was analyzed. It was shown that synchronization criterion of such STNO system is a small variation of the modulus of the complex order parameter over time. Using this criterion a microwave synchronization of STNOs with random eigen frequencies (Gaussian distribution) and initial phases (rectangular distribution) has been studied numerically.
