(a) Enlarged views of the XANES region in the EXAFS spectra before normalization and background subtraction. The XANES spectra are obtained from the same positions as in Fig. 4. For clarity, raw XANES spectra (i), (ii) and (iii) are shifted by 0.90, 0.60 and 0.30, respectively. The pre-edge structure of the MnO XANES is indicated by the arrows. (b) Absorption image at 6.540 keV and the support area. The dashed line is the boundary of the support area; the absorption inside the support area is set to 0 to highlight the noise level outside the support area (scale bar represents 1 µm). |
