Source figures may contain other techniques and soft X-ray spectra. C, N and O measurements are outside our current hard-XAFS testing range.
Fig. 1. Structure characterization. (a) X-Ray diffraction (XRD) patterns and enlarged XRD patterns of as-prepare Ar-LNM and Air-LNM samples. The comparison of structural refinement results for (b) Phase fraction (wt%) (R/M phase). (c) Total Ni content in each phase and (d) Ni content in TM layer of each phase. Normalized XANES spectra and Fourier transformed spectrum (EXAFS) at Mn (e, g), Ni(f, h) K-edge of the Ar-LNM and Air-LNM samples. i, j, k, l) XANES and EXAFS spectra at Mn (i, k) and Ni(j, l) K-edge of the two samples after milling without calcination.
