Abstract

On the basis of first-principles calculations we study the effect of interfacial Cr on the magnetoelectric properties of a composite multiferroic Fe_L/BaTiO₃(001), with the Fe thickness L\ensuremath≤2 monolayers. The use of the CrO₂-terminated interface instead of TiO₂ may significantly enhance magnetoelectricity in the system, showing an unexpected change in magnetization induced by the electric polarization reversal. In the case of L=2, for instance, the magnetic order of the Fe bilayer can be switched from nearly zero ferrimagnetic to ferromagnetic upon polarization reversal.
