Abstract

A metastable perovskite phase of Bi(Mg 1/2 Ti 1/2 )O 3 composition (BMT) has been obtained under high-pressure (6 GPa) and high-temperature (1270 K) conditions. X-ray and electron diffraction studies have revealed a complex superstructure originating from antiferroelectric-like displacements of Bi 3...
