Figure 8

Polarization versus electric field (P-E) hysteresis loop of (A) BF and (B) BFCN. The inset shows the behaviour of P-E loop for a period of 5 × 103 cycles. (C) Comparison of P-E loops for BF and BFCN materials, (D) maximum polarization (Pmax) for 5 × 103 cycles. The change in polarization value with respect to temperature (inset).
