Atomic-scale structure and chemical characterization of LSMO/BFO heterointerfaces. High-resolution HAADF-STEM images of heterostructures with the La0.7Sr0.3O-MnO2-BiO-FeO2 (A) and MnO2-La0.7Sr0.3O-FeO2-BiO (B) interfaces, and the corresponding chemical profiles across the respective interfaces (C and D). The EELS line scans are acquired diagonally from the top left to the bottom right of the HAADF images (indicated with a white line).
