The polarization relaxation phenomena in a 40-nm-thick epitaxial BiFeO3 thin film grown on a (001) SrTiO3 substrate with SrRuO3 bottom electrode, was studied in nanoscale using dual-frequency resonance-tracking piezoresponse force microscopy. The as-grown film shows highly irregular mosaic domain pa...
