The NEXAFS measurements at O K edge clearly exhibit a preedge spectral feature which evolves with Mn doping, similar to one observed in hole-doped cuprates and manganites. The Mn L-3,L-2 edge NEXAFS spectra exhibit divalent Mn apart from mixed valent Mn3+/Mn4+ states. The spectral features of XMCD at Mn L-3,L-2 edge demonstrate that ferromagnetism comes from Mn2+ ions and its dichroism shape is independent of Mn concentration.
