Observation of Polarization Vortices in Complex Oxide Superlattices


Scientific Achievement

Identified the existence of non-uniform polarization vortex states in a ferroelectric material

Significance and Impact

Topology of such non-uniform polarization fields, will act as a precursor to the search of topological states (such as skyrmions and merons) in ferroelectrics
