(a) Atomic force microscopy topography image of mixed phase BFO sample. Red and green shaded areas indicate two sets of mixed phase features oriented at 90° to each other. (b) High-resolution atomic force microscopy topography image of a mixed phase structure. (c) Cross-section line profile along the white line in (b). R- and T-phases show different slopes of ∼1.6° and ∼2.8°. (d) X-ray diffraction 2θ-ω map of a mixed phase film. (e) Schematic of T/R mixed phase structure. LAO, LaAlO3.
