Resonant Raman scattering and photoluminescence were studied in semimagnetic CdSe/ZnSe structures with self‐organized flat quantum discs of CdZnMnSe composition. Different kinds of magnetic excitations were observed in Raman scattering under sharp resonance with excitons localized in the discs. They include spin‐flip transitions from donor‐bound electrons in the discs and collective multiple spin‐flip transitions in the system of Mn 2+ ions.
