From: Intriguing photo-control of exchange bias in BiFeO3/La2/3Sr1/3MnO3 thin films on SrTiO3 substrates
Epitaxial growth of BiFeO 3 /La 2/3 Sr 1/3 MnO 3 thin film. (a) High-resolution X-ray diffraction (HR-XRD) and (b) cross section scanning transmission electron microscopy (STEM) image of BiFeO3/La2/3Sr1/3MnO3 (BFO/LSMO) thin films on SrTiO3 (STO) substrates. Spatial mapping of (c) Fe, (d) Mn, and (e) Ti elements. The inset of (a) shows a schematic illustration of the magnetoresistance measurement for the BFO/LSMO thin film under red and blue light illumination.
