Generation of a stationary train of chaotic soliton-like microwave pulses in self-oscillating ring systems with a ferromagnetic thin film

The generation of a stationary train of chaotic soliton-like microwave pulses has been observed in an isolated self-oscillating ring system with a ferromagnetic thin-film and a resonator. The pulses have been formed owing to three-wave parametric processes and modulation instability of a surface magnetostatic wave. The soliton-like character of the microwave pulses is indicated by the time dependence of the instantaneous phase of the signal envelope.
