Structures and phase transitions in perovskites – a group-theoretical approachThis article is dedicated to Helen D. Megaw (1907–2002), in appreciation of her many contributions to the crystallography of inorganic and mineral compounds, including her seminal studies of perovskites. Some of the material was presented by CJH in the Megaw memorial session at the 21st European Crystallography Meeting, Durban, South Africa, August 2003.
