Quantified spin-wave symmetry in rectangular permalloy microstrips investigated using TR-STXM, FMR and Mumax3

The asymmetry quantification of spin-wave dynamics in confined rectangular permalloy microstrips is suggested and applied to the TR-STXM results and micromagnetic simulations. The excitation was done at a frequency of 9.43GHz using a uniform microwave magnetic field while the external static magnetic field is varied. The results show a higher asymmetry for the double microstrips indicating an influence of an additional microstructure placed in a close proximity to the analyzed structure.
