Spectrum and Attenuation of Non-Linear Surface Magnetostatic Spin Waves in Ferrite Films
نویسندگان
چکیده
Dispersion and attenuation of non-linear surface magnetostatic waves (MSSW) propagating in thin ythium-irongarnet (YIG) fenite Nms have been studied both experimentally and theoretically. They were defined from the amplitude and phase alterations of the wave as it traveled along the "non-equilibrium" part of the film. At the border of such a non-equilibrium part the wave power is equal to the threshold value. The value for the threshold power is defined by the firstand second-order parametric decay processes for the MSSW.

متن کاملMagnetostatic surface waves propagation at dissipative ferrite-MTMs-metal structure
The magnetostatic surface waves (MSSW) propagation in a layered structure composed of ferrite film covered by air and on top of metamaterial (MTM) placed on metal is discussed. Dispersion equations which relate the parameters of different layers are derived and used to analyse propagation of MSSW. It is found that the MSSW excitation band depends on the thickness of the MTM layer and ferrite la...

The relaxation mechanisms in thin nickel films are investigated with all optical pump-probe experiments. Magnetic oscillations in the GHz range can be attributed to the uniform precession (Kittel mode) and spin waves with dipole character (Damon-Eshbach surface modes). Applying an external field changes both oscillation amplitude and frequency yielding experimental dispersions ν(Hext). On a wed...
