Mechanisms of Gap Solitons Formation in Periodic Ferromagnetic Structures

Morozova M., Nikitov S., Sharaevskii Y., Sheshukova S.

The features of envelope soliton formation in one-dimensional periodic ferromagnetic structure were considered. The model based on the coupled nonlinear Schrödinger equations was used for investigation. The parameter space showing the region in which solitons similar to the Bragg solitons with different features can form was calculated. The mechanisms of the formation of the solitons localized on the limited length of the structure were considered.

Magnetostatic surface waves (MSSW) propagation in YIG films with "leaky" and "resonant" metasurfaces (MS) is studied. "Leaky" MS was fabricated by ion etching of the subwavelength periodic structure in YIG film surface while "resonant" MS was formed by placing the subwavelength periodic array of YIG stripes onto the plane YIG film. The effects of filtration and the dispersion properties of MSSW in such structures are discussed.
