      abstract     = {The electrochemical changes induced by an electric field in
                      Fe-doped SrTiO(3) have been investigated by X-ray absorption
                      spectroscopy (XANES and EXAFS), electron paramagnetic
                      resonance (EPR) and Raman spectroscopy. A detailed study of
                      the Fe dopant in the regions around the anode and cathode
                      reveals new insights into the local structure and valence
                      state of Fe in SrTiO(3) single crystals. The ab initio full
                      multiple-scattering XANES calculations give an evidence of
                      the oxygen vacancy presence in the first coordination shell
                      of iron. Differences in the length and disorder of the Fe-O
                      bonds as extracted from EXAFS are correlated to the
                      unequivocal identification of the defect type by
                      complementary spectroscopical techniques to identify the
                      valence state of the Fe-dopant and the presence of the Fe -
                      V(Ö) complexes. Through this combinatorial approach, novel
                      structural information on Fe - V(Ö) complexes is provided
                      by X-ray absorption spectroscopy, and the relation of Fe-O
                      bond length, doping level and oxidation state in
                      SrTi(1-x)Fe(x)O(3) is briefly discussed.},
