The ferroelectric and cubic phases in BaTiO3 ferroelectrics are also ...
Ferroelectric (FE) materials have broad applications in transducers, actuators, capacitors, and memories. Particularly well studied is BaTiO 3, which has rhombohedral (R), orthorhombic (O), tetragonal (T), and cubic (C) phases.However, the microscopic nature of the phases and transitions in BaTiO 3 remains uncertain. A popular model in history is the displacive model (1, 2), in which the ...
