Extended Data Figure 3

Local determination of the Mn oxidation state from a spectrum image obtained around a TbMnO3 domain wall following the analysis of the O K edge previously described. a, Simultaneously acquired HAADF signal. b, Mn oxidation state map. c, O K edges obtained by integrating spectra in the upper domain (orange), in the domain wall (green) and in the lower domain (red).
