Fig. 5. (Color online) Ferroelectric hysteresis loops measured (a) in BiFeO₃ ceramics sintered under four different conditions, (b) before poling in furnace-cooled BiFeO₃ ceramic after sintering at 810 °C, (c) before poling in air-cooled BiFeO₃ ceramic after sintering at 810 °C, (d) after poling in furnace-cooled BiFeO₃ ceramic after sintering at 810 °C, and (e) after poling in air-cooled BiFeO₃ ceramic after sintering at 810 °C.
