Fig. 3. (a) Background subtracted k3 weighted XAFS spectra of various concentrations, x. Solid lines represent the Fourier transform region for EXAFS fitting. (b) Fitting of Fourier transformed k3-weighted EXAFS spectra for Li2(Li1−xFex)N as a function of concentration, x. EXAFS fitting is represented as dashed lines with corresponding parameters presented in Table 1.
