“Playing with octahedra distortions of RBO3 perovskites"

Abstract

RBO3 perovskites, namely with B = Fe and Mn, present a distorted perovskite structure, Pnma. The distortions of the BO6 octahedra are very interesting as they are intimately coupled with their physical properties. It will be discussed how it is possible to "play" with the octahedra distortions, in particular how to follow them using Raman spectroscopy and symmetry adapted distortion modes applied to X-ray diffraction data, as a function of composition and high-pressure.
