Hexagonal LuMnO₃ revisited

B. B. Van Aken, A. Meetsma and T. T. M. Palstra

Abstract: The crystal structure of hexagonal LuMnO₃ at room temperature is isomorphous with YMnO₃ and deviates in important details from the early work of Yakel et al. [Acta Cryst. (1963), 16, 957-962]. Mn is near the centre of its oxygen coordination environment. On the threefold axes, the apical O-Lu bonds have alternating long and short bond lengths, leading to ferroelectric behaviour. The sample studied was composed of almost equal volumes of inversion twins.
