Abstract: Modulated structures consisting of square arrays of 60 nm thick Ni 80Fe20 circular dots underneath a continuous Ni 80Fe20 film were fabricated using multi-level process based on deep ultraviolet lithography at 248 nm exposure wavelength. We observed a drastic change in both the static and dynamic properties of the modulated structures by varying the Ni80Fe20 film thickness t in the range from 5 to 60 nm. It was revealed via comparison between experimental results and micromagnetic simulations that the dots create perturbations of internal fields in the neighbor regions of the film which can be controlled by magnetic field and film thickness. © 2013 AIP Publishing LLC.
