Features of formation of band gaps in coupled structures based on magnonic crystals

There are introduced ferromagnetic periodic structures consist of two coupled magnonic crystals and related magnonic and crystal film, separated by a dielectric layer. The dispersion equation made for magnetostatic waves, that propagate in such structures and identified main features of formation band gaps and a comparison with a periodic structure of one magnonic crystal was made.

Nonlinear dynamics of spin waves in lateral magnetic microwaveguides

In the present work, a numerical and experimental study of the nonlinear dynamics of spin waves in lateral magnetic microwave guides was made. The mechanism of nonlinear spin-wave coupling between different types of modes in lateral waveguides was revealed. The investigation of lateral magnetic microstructures supporting both linear and nonlinear propagation of spin waves is of great interest nowadays.
