The intensity of the pre-edge spectral feature at the O K-edge increases with Mn concentration, which clearly reveals that there is a strong hybridization of Mn ions with the ZnO matrix. The near-edge X-ray absorption fine structure (NEXAFS) measurements at the Mn K- and L-3,L-2-edges show a mixed valence nature for the Mn ions, with Mn2+ and Mn3+/Mn4+ states, and the Mn3+/Mn4+ states are observed to increase with the Mn-concentration. Mn L-2,L-3 resonant inelastic X-ray scattering (RIXS) measurements show that the excess Mn interstitials appear in the sample and that direct exchange interactions with substitutional Mn atoms may explain the magnetic interaction in Mn-doped ZnO.
