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.

Control of the electromagnetic spin waves spectrum in a heterostructure based on the lateral system of magnetic microwaveguides

At present, the actual task is to study magnetic microstructures, the characteristics of which can be controlled by changing static magnetic and electric fields. Thin films of yttriumiron garnet show much lower damping of spin waves in comparison with metallic magnetic films. The propagation length of spin waves in magnetic microwaveguides and magnonic crystals is of the order of a few millimeters at room temperature. The use of lateral magnetic microstructures is important for the development of interconnection elements in planar topologies of magnonic networks.
