Abstract: Multilayer films of ZnO with Co were deposited on glass substrates thenannealed in a vacuum. The magnetisation of the films increased with annealingbut not the magnitude of the magneto-optical signals. The dielectric functionsfor the films were calculated using the MCD spectra. A Maxwell Garnett theoryof a metallic Co-ZnO mixture is presented. The extent to which this explainsthe MCD spectra taken on the films is discussed.
