We report on magneto-optical studies of an epitaxial thin film of GdMnO3 grown on SrTiO3. Significant differences were found between the magneto-optical and absorption spectra, which highlight the importance of magneto-optics in determining the magnetic character of the optical transitions. Two main features were identified in the magnetic circular dichroism (MCD) spectra: the charge transfer transition between Mn d states at ~2eV and the band edge transition from the oxygen p band to the d states at ~3eV. The strength of the MCD at ~2eV correlates well with the Mn spin ordering, indicating the applicability of magneto-optics for understanding the magnetic properties.
