Abstract
A detailed investigation using variable temperature powder neutron diffraction demonstrates that BiFeO3 undergoes a phase transition from the ferroelectric ? phase (rhombohedral, R3c) to a paraelectric ? phase (orthorhombic, Pbnm) between 820?°C and 830?°C. Coexistence of both phases over a finite temperature interval, together with abrupt changes in key structural parameters, confirms that the transition is first order. The ? phase corresponds to a GdFeO3-type perovskite structure.
