The carbonyl iron flakes are fabricated by high-energy ball milling.The effective permeability is measured and calculated for the composite consisting of flakes embedded in a nonmagnetic matrix.The magnetic flakes with a shape anisotropy and random spatial distribution of normal direction are considered to calculate the complex permeability of magnetic flake materials.Its analytical model is derived from the Landau-Lifshitz-Gilbert equation and Bruggemans effective medium theory.The calculated results agree well with the experiment.
