Abstract
We present a detailed comparison between the results of ferromagnetic resonance (FMR) measurements on a square array of permalloy nanodots and a numerical simulation based on the eigenvalues of the linearized Landau-Lifshitz equation. Of particular importance is the implementation of a recently developed technique for numerically calculating the absorption spectrum from the associated eigenvectors as a function of the orientation, frequency, and position dependence of the applied RF field. The method is also used to predict results of some possible future experiments.
