The utility of ferroelectric materials stems from the ability to nucleate and move polarized domains using an electric field. To understand the mechanisms of polarization switching, structural characterization at the nanoscale is required. We used aberration-corrected transmission electron microscopy to follow the kinetics and dynamics of ferroelectric switching at millisecond temporal and subangstrom spatialolla resolution in an epitaxial bilayer of an antiferromagnefic ferroelectric (BiFeO3<) on a ferromagnetic electrode (La0.7Sr0.3MnO3 [ABSTRACT FROM AUTHOR]
