a Piezoelectric amplitude and b piezoresponse force microscopy image of BPBO/BLFO. Box-in-box mapping is done with ±5 V electric field. c Line scan profile of the BLFO phase of (b). d Point-contact amplitude and piezoelectric hysteresis. e, f PFM and piezoelectric hysteresis data for SRO/BLFO deposited at 700 °C. Both samples loops were recorded at a frequency 0.83 Hz and 1 V AC drive amplitude with ±9 V DC scan voltage.
