Robust synchronization of spin-torque oscillators with an LC R load
- We study dynamics of a serial array of spin-torque oscillators with a parallel inductor-capacitor-resistor (LC R) load. In a large range of parameters the fully synchronous regime, where all the oscillators have the same state and the output field is maximal, is shown to be stable. However, not always such a robust complete synchronization develops from a random initial state; in many cases nontrivial clustering is observed, with a partial synchronization resulting in a quasiperiodic or chaotic mean-field dynamics.
