(a). Magnetic domain image for a region of BFCO film using MFM at RT. (b) PFM phase images for a region of BFCO film at RT. [(c)–(f)] PFM phase images of the same area in BFCO film after applied biases of 1 V, 3 V, 7 V, and 9 V, respectively.
KPFM images for a region of BFCO film after the writing processes with (a) 0.05 V, 0.5 V, 1 V, and 2 V and (b) −0.05, −0.5, −1 and −2 V. The order of the applied voltage is first from left to right and then from top to bottom. (c) Writing bias dependence of the SP.
KPFM images for a region of BFCO film after the writing processes with (a) 2.0 V and (c) −2.0 V. [(b) and (d)] Corresponding KPFM images after the discharging process.
(a) Time dependence of representative line profiles of the SP after −3 and −5 V. (b) Time evolution of the SP after −5 V. The line is an exponential fit to the data. (c) KPFM images of BFCO thin film with applied biases of −3 V (left) and −5 V (right) after poling, 40, 120, and 200 min. The order of the elapsed time is from top to bottom.
