Spin-torque oscillator (STO) is a nanospintronic device generating microwave field in the GHz range. Potential applications of STO in telecommunication are limited by its very weak output power. Synchronization of arrays of STOs, with the aim to increase the microwave power and to reduce the linewidth, remains a challenging task due to strongly nonlinear properties of STOs. In this project we will theoretically study synchronization properties of arrays of spin-torque oscillators based on modern methods of nonlinear dynamics and synchronization theory, with the goal to suggest robust synchronization schemes stably operating within a large range of parameters and disturbances.

自旋力矩振荡器（STO）是一种产生GHz微波场的纳米自旋电子器件。由于STO的输出功率很小，限制了其在通信领域的应用。由于STO的强非线性特性，以提高微波功率和减小线宽为目的的STO阵列的同步仍然是一项具有挑战性的任务。在这个项目中，我们将从理论上研究基于非线性动力学和同步理论的现代方法的自旋力矩振荡器阵列的同步特性，其目标是提出鲁棒的同步方案，在大范围的参数和干扰稳定运行。
