【 摘 要 】

tsAn epitaxial nanocomposite approach is developed for exploring spatial control of oxygen vacancy-driven topotactic phase transition of La0.7Sr0.3MnO3-x (LSMO).The ultrahigh density of epitaxial interfaces created in the self-assembled LSMO-NiO nanocomposite films strongly influence the oxygen vacancy formation and topotactic phase distribution in LSMO.The distinct intermediate topotactic nanostructures controlled by the NiO fraction broadens the tuning range of correlated magnetic and transport properties of LSMO.
