The O K-edge spectra indicate that the Fe 3d orbitals have been considerably modified and a new spectral feature start dominating in the pre-edge region at higher Ti doping. The Fe 2p NEXAFS spectra exhibit a mixed valent Fe2+/Fe3+ states apart from the conversion of Fe3+ to Fe2+ with the substitution of Ti ions. The Ti L-3,L-2-edge spectra indicate that Ti ions remain unchanged at 4+ state. These variations in the host electronic structure due to Ti substitution are consistent with the dielectric and transport properties of the material. (c) 2008 Elsevier B.V. All rights reserved.
