We report an electric modulation of magnetization at the Fe3O4/BaTiO3 interface and a magnetoelectric coefficient of 0.72 Oe.cm/kV by ferroelectric polarization reversal at room temperature. We find that the change of magnetization is approximately proportional to the BaTiO3 layer c axial electrostriction. We believe that this effect is due to atomic displacements at the interface as a result of ferroelectric switching which affects the interface magnetization. (C) 2017 Elsevier B.V.
