description <jats:p>We observed the retention loss of dot domains (36nm diameter) and square domains with sizes of 1 and 25μm2 that were reversed by applying an electric field at an atomic force microscopy (AFM) conductive tip on a heteroepitaxial PbTiO3 thin film with + polarization in the virgin state, which was fabricated via hydrothermal epitaxy below Tc. Through theoretical calculations, it was discussed that the retention loss phenomena of a domain reversed by using an AFM tip were derived from the summation of the depolarization field energy and the strain-polarization coupling energy.
