Abstract: Double ferroelectric hysteresis (P-E) loops are observed in aged BiFeO₃multiferroic ceramic at room temperature and are explained according to an aging effect driven by charged defects with high activation energy. The aged BiFeO₃shows R3c defect symmetry and allows a nonzero charged defect-induced polarization (P[sub D]) below the ferroelectric Curie temperature. This P[sub D] is strong enough to recover the switched 180° ferroelectric domains upon the removal of E, but it is rather weak to effectively switch back the 71°/109° ferroelectric domains. As a result, the traits of the double P-E loops weaken with increasing the maximum E from 121 to 167 kV/cm.
