Stable Magnetostatic Solitons in Yttrium Iron Garnet Film Waveguides for Tilted in-Plane Magnetic Fields

The possibility of nonlinear pulses generation in Yttrium Iron Garnet thin films for arbitrary direction between waveguide and applied static in-plane magnetic field is considered. Up to now only the cases of in-plane magnetic fields either perpendicular or parallel to waveguide direction have been studied both experimentally and theoretically. In the present paper it is shown that also for other angles (besides 0 or 90 degrees) between a waveguide and static in-plane magnetic field the stable bright or dark (depending on magnitude of magnetic field) solitons could be created.Comment: Phys.

DIPOLE-EXCHANGE SPIN WAVE SOLITONS IN YIG FILMS

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

Parametric amplification of propagating spin waves in ferrite films

Amplification of a weak signal spin wave by a strong pump spin wave propagating in yttrium iron garnet film was observed for the first time. A theoretical explanation of this effect is given on the basis of the four-wave parametric processes
