a Polarization as function of electric field for the samples BPBO/BLFO/BPBO at 450 °C→I, SRO/BLFO/SRO at 700 °C→II, and SRO/BLFO/SRO at 450 °C→III. b dielectric constant, and c Leakage current as a function of electric field across the capacitors in BPBO/BLFO/BPBO and SRO/BLFO/SRO heterostructures. d Pulsed switched polarization as a function of varying voltage at a fixed 2 ms pulse width. e Voltage dependence of switched polarization by varying the pulsed widths in sample-I.
