Abstract
A high-spin ruthenate phase is achieved at the SrRuO${}_{3}$/SrTiO${}_{3}$ interface via a solid ionic chemical junction, which benefits from the distinct formation energies and diffusion barriers of oxygen vacancies across the heterostructure. This high-spin SrRuO${}_{3}$ phase can be reversibly switched by electric field in a solid-state ionic gating device, providing a framework for atomic design of controllable functionalities in strongly correlated oxides using solid-chemistry tools.
