The optical properties of pure - as well as disordered - alloys have received a lot of interest as they play an important role, for example in storage applications. We present a first-principle approach to calculate magneto-optical properties based on the Kubo formula implemented within the fully relativistic KKR (Korringa-Kohn-Rostoker) formalism in combination with coherent potential approximation accounting for chemical disorder in substitutional random alloys. The implemented formalism allows to calculate the full frequency dependent conductivity tensor and to discuss on this basis the magneto-optical effects. The first results will be presented for ferromagnetic transition metal alloys.
