Abstract: We have investigated the dynamic response of alternating-diameter Ni 80Fe 20 antidot arrays using broadband ferromagnetic resonance (FMR). We observed a significant modification in both the number of spin wave modes and mode profiles when compared with homogeneous diameter antidot arrays. The FMR response shows a static field amplitude-dependent mode transformation (extinction or emergence) due to a complex non-uniform distribution of the demagnetizing field. Our experimental results have also been modeled using dynamic micromagnetic simulations, and we obtained a good agreement between both results. © Europhysics Letters Association 2012.
