Chaotic Dynamics of Spin-Valve Oscillators
摘要：
最近对电流驱动的磁化动力学的实验和理论研究揭示了许多前所未有的丰富的动力学现象。我们预测的内在混沌动力学，以前没有预料到的。我们明确地表明，通过一系列的倍周期分岔发生的过渡到混沌动力学。在混沌区，两个显着不同的功率谱，一个具有明确的峰值和广泛分布的噪声，被确定和解释。
英文摘要：
Recent experimental and theoretical studies on the magnetization dynamics driven by an electric current have uncovered a number of unprecedented rich dynamic phenomena. We predict an intrinsic chaotic dynamics that has not been previously anticipated. We explicitly show that the transition to chaotic dynamics occurs through a series of period doubling bifurcations. In chaotic regime, two dramatically different power spectra, one with a well-defined peak and the other with a broadly distributed noise, are identified and explained.
