The ability to controllably manipulate complex topological polar configurations such as polar flux-closures via external stimuli may allow the construction of new electromechanical and nanoelectronic devices. Here, using atomically resolved in situ scanning transmission electron microscopy, we find that the polar flux-closures in PbTiO<sub>3</sub>/SrTiO<sub>3</sub> superlattice films are mobile and can be reversibly switched to ordinary single ferroelectric <i>c</i> or <i>a</i> domains under an ...[more]
