论文摘要
我们表明，自旋变速器振荡器的相通常会在控制其动力学的参数的缓慢和环状变化时获得几何贡献。例如，我们计算由外部磁场和电流幅度的循环游览产生的几何阶段。我们考虑热相波动，并得出结论，几何相应在室温下在室温下以电流设置进行实验观察。我们简要评论旋转振荡器和可能的应用。
We show that the phase of a spin-torque oscillator generically acquires a geometric contribution upon slow and cyclic variation of the parameters that govern its dynamics. As an example, we compute the geometric phase that results from a cyclic excursion of the magnitude of the external field and the current. We consider thermal phase fluctuations and conclude that the geometric phase should be experimentally observable at room temperature with current setups. We briefly comment on arrays of spin-torque oscillators and possible applications.
