A pair distribution function study to determine the local structure of the titanium atom in BaTiO3 as a function of temperature
Abstract: BaTiO3 is the prototypical ferroelectic perovskite and has been well studied for over 60 years. The standard structural picture is that it is cubic and paraelectric at high temperature and on cooling becomes tetragonal below 393 K, orthorhombic below 278 K and rhombohedral below 183 K. There is still, however, considerable debate regarding the local structure around the Ti atom with a widely accepted view that the TI atom is always displaced along the pseudo-cubic <111> directions within an oxygen octahedra. Others, however, disagree. We have recently collected room temperature PDF data on GEM as part of a study of double-doped systems, and this appears to be inconsistent with the standard explanation. We wish to confirm this and also determine the local distortions in all phases through a variable temperature study.
