In ferroelectric BaTiO3 tunnel junctions, integrating tensile strained slave La0.5Sr0.5MnO3 (HD) layers, polarization reversal promotes an orbital-reordering and a concomitant metal–insulator transition in the HD layer that largely enhances the electroresistance of the junctions. Radically different results are obtained under compressive strain.
