Abstract

The phenomenon of chaotic microwave self-generation under conditions of a four-wave parametric spin wave interaction in active resonance rings based on ferromagnetic films has been studied for the first time. It is shown that microwave signals of various types—in particular, monochromatic, stationary soliton-like pulse trains, and dynamic chaos—can be generated by controlling the gain level in the active ring. Parameters characterizing the chaotic signal generated in the ring are determined.
