Annotation	Scientists have found that the spontaneous ferroelectric polarization can be fully and reversibly flipped by varying partial oxygen pressure above the surface of an epitaxially compressed PbTiO3 film. The inward polarized state is stabilized by ordered oxygen vacancies in the topmost atomic layer.
