When BiFeO3 layers are confined between TbScO3 layers in an epitaxial superlattice, crystallographically orthogonal voltages can induce reversible, non-volatile switching between polar and antipolar states in BiFeO3. This symmetry switch also leads to marked changes in the nonlinear optical response, piezoresponse and resistivity of the system.
