Abstract
The experiments demonstrating nonlinear dynamics of propagating dipole-exchange spin waves (SW) in YIG films are described. It is shown that SW input pulse with the increase of its duration and amplitude splits into envelope solitons, demonstrates modulational instability and formation of strange attractor according to the Ruelle-Takens scenario.
