Title: Interplay between charge ordering and geometric ferroelectricity in LuFe2O4/LuFeO3 superlattices

Abstract

Oxide superlattices have drawn great attentions owing to the intriguing coupling among elastic, electrical, and magnetic orderings at the interfaces and the emerging of improper ferroelectricity. Here, superlattices composed of hexagonal LuFeO3 (h-LuFeO3) and LuFe2O4 are investigated via density functional theory calculations. h-LuFeO3 is a well-known multiferroic material that is stable only in thin-film or doped bulk state, while LuFe2O4 is a charge ordered material where the existence of ferroelectricity is still in controversy. We have found that the charge ordering (CO) induced polarizations in LuFe2O4 layers coexist with the geometric polarizations in h-LuFeO3 layers in the (LuFe2O4)m/(LuFeO3)n superlattices with different periodicities, and the ferroelectric states are generally preferred over the antiferroelectric states for LuFe2O4 in superlattices. The out-of-plane polarizations in h-LuFeO3 and LuFe2O4 layers tend to be aligned in parallel, and the overall polarization increases with the ratio of h-LuFeO3. The influence of layered polarizations on the local electrostatic potential is not significant except the detected small trend caused by the CO-induced polarization within a FeO bilayer. Besides, the local electronic structures show that the Fermi level position in a certain layer can be tuned by the valences of Fe in this layer and the polarization distributions in neighboringmore » layers. LuFe2O4 layers sandwiched between thick h-LuFeO3 layers are more susceptible. The calculated configurations of the superlattices are supported by atomic-resolution transmission electron microscopy experiments. Our results pave a way for tunable ferroelectricity in superlattice systems and create a new playground for manipulating the coupling between various degrees of freedom.« less
