| 摘要 | Deliberate manipulation of topotactic transformation via oxygen insertion/extraction offers a feasible way to precisely tune oxygen concentration, B–O coordination occupation and resultant electronic functionalities of perovskite (ABO)-based oxides. Herein, two methods, a post-annealing CaH treatment and an in-situ oxygen-vacancy diffusion using oxygen getter layer, were conducted to achieve topotactic transitions from perovskite to brownmillerite of LaSrMnO (LSMO, 0 ≤ δ ≤ 0.5) films. The results revealed that delicate control of oxygen composition is the crucial factor for evolutions of crystalline structure and subsequent magnetic properties of LSMO films. In particular, the brownmillerite LSMO film treated by the in-situ oxygen getter layer possesses desirable structural stability over time. In contrast, the topotactic LSMO films using reduction agents CaH exhibit compositional and structural inhomogeneities. These findings suggest that adjustable topotactic transformation through anionic oxygen provides a facile strategy for designing multifunctional perovskite-derivative oxide materials. |
