A Mean-Field Model of Extrinsic Line Broadening in Ferromagnetic Resonance

Author(s)

Abstract

A model of ferromagnetic resonance in inhomogeneous films is described that includes interactions in a mean-field approximation. The mean-field model yields linewidth values that span the range from intrinsic linewidth for strong interactions to fully broadened local resonance line widths for interactions. For weal inhomogeneity, the mean-field model does not follow the quadratic dependence of broadening on inhomogeneity predicted by the two-magnon model. For weakly interacting regions with strong inhomogeneity, the mean field model fills a gap in the modeling of ferromagnetic resonance spectra where only computationally intensive models have been available previously.
