Description
The design of a microstructure can affect the internal field distribution and, therefore, the spin-wave (SW) behaviour. Under the uniform excitation only symmetric SW interference pattern is expected. Changes in the geometry of the structure can cause breaking of the symmetry. In this work the asymmetry parameter (AP) of SW dynamics in confined rectangular permalloy microstrips is suggested and applied to the TR-STXM results and micromagnetic simulations. In this work profiles of the out-of-plane component of the dynamic magnetization are analyzed. The results show a higher asymmetry for a strip when a second perpendicular microstrip is placed at the distance of 2 µm.
