Abstract: Nonequilibrium atomic structures can host exotic and technologically relevant properties in otherwise conventional materials. Oxygen octahedral rotation forms a fundamental atomic distortion in perovskite oxides, but only a few patterns are predominantly present at equilibrium.… read more here.

DOI: 10.1063/5.0035501
Abstract: Recent studies have highlighted the collective rotations of corner-shared oxygen octahedra in ABO3 functional perovskite oxides. However, experimental methods that allow direct measurements of oxygen octahedra, especially for the multilayer containing different types of oxygen… read more here.
