(a) Comparison of the experimental XANES spectra through the series La1–xCaxMnO3 (black solid lines; from left to right x = 0, 0.33, 0.5, 0.66 and 1) and LaMn0.4Ga0.6O3 (red closed circles). (b) Correlation between the formal valence state of the Mn atom and the chemical shifts of the Mn K-edge with respect to LaMnO3 in several manganites. |
