Popis: An ab initio study on the magnetoelectric coupling at interfaces of ferromagnetic perovskite Sr-doped LaMnO3 (LSMO) and ferroelectric perovskite BaTiO3 (BTO) with (001) and (111) perovskite orientations is presented. It was found that the interfaces with both orientations exhibit significant magnetoelectric couplings. The effects of the orientation on the magnetoelectric coupling are discussed on the basis of the electronic structure, suggesting that the enhancement of electrostatic-screening-induced magnetoelectric coupling at the (111) interface in comparison with the (001) interface is mainly due to strengthened interfacial coupling.
