Abstract :
This paper reports the experimental results of spatial and temporal dynamics research of dissipative parametric solitons generated in a ferromagnetic film active ring resonator. Such dissipative structures are formed through three-wave parametric decay of a magnetostatic surface wave and frequency-time filtering. The spatio-temporal dynamics of dissipative parametric solitons has been investigated using the Brillouin light scattering technique. It is shown that quasi-stationary temporal structures are formed in a ring along a ferromagnetic film and are not observed in a ferromagnetic film, which is not incorporated into the ring.
