(a) Normalized XAS data measured at room temperature near the Ni K-edges of Ba2La2NiW2O12, Sr2La2NiW2O12, standard Ni0 foil, and standard Ni2+O. The inset displays a close up of the edge position. (b) The Fourier transformed EXAFS component, with peaks corresponding to distances from Ni to neighboring pairs, are labeled in the figure. |
