Figure 4: NEXAFS data on Sm-substituted BFO samples with different compositions.

From: Atomic-scale evolution of modulated phases at the ferroelectric–antiferroelectric morphotropic phase boundary controlled by flexoelectric interaction

Pre-MPB (olive), MPB (red) and post-MPB (blue). (a) Evolution of the Fe-L-edge fine structure; (inset) comparison of Fe-L edges for pre-MPB and MPB samples showing clear widening (spectra renormalized); (b) evolution of the O K-edge fine structure; pure BFO data (black) are added for comparison.
