Enhancement of electromechanical properties in (0–3) lead-free ferroelectric nanocomposites with multiphase coexistence

In this study, electromechanical responses of BiFeO3/BaTiO3 (BFO/BTO) (0–3) nanocomposites with different volume fractions of BFO nanoparticles are investigated using phase field model based on the Landau–Ginzburg theory. A rich phase coexistence, including tetragonal (T), orthorhombic (O), and rhombohedral (R) phases, is characteristically formed in the domain structure of the nanocomposite due to interactions between BFO nanoparticles and BTO...
