Crossover in the pressure evolution of elementary distortions in RFeO3 perovskites and its impact on their phase transition

R. Vilarinho, P. Bouvier, M. Guennou +9

This work reports on the pressure dependence of the octahedra tilts and mean Fe-O bond lengths in RFeO3 (R=Nd, Sm, Eu, Gd, Tb and Dy), determined through synchrotron X-ray diffract…
