Ruddlesden‐Popper Manganites: Tailoring C‐axis Orientation in Epitaxial Ruddlesden–Popper Pr0.5Ca1.5MnO4 Films (adv. Mater. Interfaces 7/2021)

For Ruddlesden-Popper Pr0.5Ca1.5MnO4 thin films grown on STO (100) the c-axis lies in-plane and two possible configurations are observed. On the atomic level the film consists of perovskite (yellow) and rock-salt (blue) sub unit cell blocks forming a network throughout the film. Both lattice and packing induced stress fields result in formation of perpendicularly aligned cracks (mirroring the micro-structure).
