Abstract
The sensitivity of magneto-optical spectra to alloy chemical ordering is established. This is demonstrated for a new ordered Co3Pt phase, wh ich was synthesized in thin film form using molecular beam epitaxial g rowth. This compound consists of alternating planes of Co and CoPt ato ms with a hexagonal ABAB... layer sequence. The chemical ordering is a ccompanied by a substantial electronic structure change as reflected i n a new peak in magneto-optical spectra at approximately 3.2 eV photon energy.
