Topotactic Phase Transition in Epitaxial La <sub>0.7</sub> Sr <sub>0.3</sub> MnO <sub>3‐δ</sub> Films Induced by Oxygen Getter Assisted Thermal Annealing
Abstract Oxygen vacancies play a crucial role in controlling the physical properties of complex oxides. In La 0.7 Sr 0.3 MnO 3‐δ , the topotactic phase transition from Perovskit...
