We have investigated the electronic structure of ZnO:Mn and ZnO:Mn,N thin films using x-ray magnetic circular dichroism (XMCD) and resonance-photoemission spectroscopy. From the Mn 2p → 3d XMCD results, it is shown that, while XMCD signals only due to paramagnetic Mn2+ ions were observed in ZnO:Mn, nonmagnetic, paramagnetic, and ferromagnetic Mn2+ ions coexist in ZnO:Mn,N. XMCD signals of ZnO:Mn,N revealed that the localized Mn2+ ground state and Mn2+ state hybridized with ligand hole coexisted, implying p-d exchange coupling. In the valence-band spectra, spectral weight near the Fermi level was suppressed, suggesting that interaction between magnetic moments in ZnO:Mn,N has localized nature.
