Theoretical XAS and XMCD spectra are shown for ZnBixO1−x (x = 3%) which are calculated with the FEFF code.
Close to circular light is used, with the same degree of circularity as for the experiment. The Bi doped ZnO spectra using the known bulk values for the ZnO lattice describe well the experimental TFY spectra. The TEY spectra, are best described, by means of an expanded ZnO lattice, here a calculation with an expansion of 7% is shown. The TEY channel is sensitive to the near surface region of the ZnBixO1−x film, only with TFY the bulk of the ZnBixO1−x film is probed. The thermal disorder on the XAS and XMCD spectra is introduced using the correlated Debye model.
