TL;DR
This study investigates the magneto-optical properties of Co/ZnO multilayer films, examining how annealing affects magnetization and analyzing their dielectric functions and spectra with theoretical models.
Contribution
It introduces a Maxwell Garnett theory for Co/ZnO mixtures and compares it with experimental magneto-optical data.
Findings
Magnetization increases with annealing.
Magneto-optical signals do not increase with annealing.
The Maxwell Garnett theory explains part of the MCD spectra.
Abstract
Multilayer films of ZnO with Co were deposited on glass substrates then annealed in a vacuum. The magnetisation of the films increased with annealing but not the magnitude of the magneto-optical signals. The dielectric functions for the films were calculated using the MCD spectra. A Maxwell Garnett theory of a metallic Co/ZnO mixture is presented. The extent to which this explains the MCD spectra taken on the films is discussed.
