10. For comparison of the structural and static magnetic properties, see ref. [6], which describes the same Co(0001) system, the only difference being the substrate material, which is sapphire in ref. [6], vs. mica in this work. A comparison of films grown on both substrate materials revealed no influence of the substrate material on the magneto-static properties or on the excitation spectrum.
