The O K-edge NEXAFS (Figure ) is of particular interest for oxide materials in general, due to the delocalized character of the O 2p orbitals. These orbitals are responsible thus for their conduction properties. We probe in this case the unoccupied electronic states available in the conduction band. The spectra exhibit two distinct regions, below and above ~535 eV. In the region marked as A, we probe the spectra recorded at Fe L2,3 edge (Figure ). Owing to the Fe2TiO5 formation at the surface of the sample, we probe a mixture of hematite and titanate character. Before any comparison with the literature, it is mandatory to note that NEXAFS cannot give absolute energy positions unless precise X-rays energy calibration is performed. That is not always the case. Therefore, reported values may vary slightly.
