Local electronic structure of Fe2+ impurities in MgO thin films: temperature-dependent soft x-ray absorption spectroscopy study
We report on the local electronic structure of Fe impurities in MgO thin films. Using soft x-ray absorption spectroscopy (XAS) we verified that the Fe impurities are all in the 2+ valence state. The fine details in the line shape of the Fe $L_{2,3}$ edges provide direct evidence for the presence of...
