Structure properties of T-BFO/CMO heterostructures.
(a) High-angle annular dark field image near a T-BFO/CMO interface. (b–d) EELS maps of Fe, Ca and Mn L3,2 edges. (e) X-ray 2θ-ω scan of a heterostructure consisting of a 38 nm-thick supertetragonal BiFeO3 (T-BFO) and a 40 u.c. CMO layers, grown on YAO. The diffraction peaks are identified as (001) reflections (in pseudocubic setting) of each component. (f) Vertically averaged profiles of the HAADF, Mn, Ca and Fe EELS signals over the rectangular area in (a).
