1 Introduction. Barium titanate (BaTiO 3, BTO) is a perovskite type oxide, presenting five different crystalline structures depending on the temperature: rhombohedral at low temperature, orthorhombic, then tetragonal and becoming cubic above T C = 120 °C. [] The cubic structure is stable up to 1460 °C, and above this temperature, a hexagonal …
