Comparison of the Fe K-edge XANES spectra [from Piquer et al. (2014BB173)] of a 4 nm (M4) magnetite sample (black, open circles) and the weighted sums of the displaced reference samples (see text for details): 20% Fe3O4 + 80% γ-Fe2O3 (red, solid circles), 20% Fe3O4 (ΔE = 1 eV) + 80% γ-Fe2O3 (ΔE = −1 eV) (blue, solid triangles), 20% Fe3O4 + 80% γ-Fe2O3 (ΔE = −2.5 eV) (green, solid triangles) and 20% Fe3O4 + 80% γ-Fe2O3 (ΔE = −0.5 eV) (magenta, filled diamonds). The inset shows a detailed view of the white-line region.
