The magnetic depth profile of an epitaxially-grown artificial multiferroic ferromagnetic/ (ferroelectric, piezoelectric) La0.67Sr0.33MnO3/0.7(Pb(Mg1/3Nb2/3)O3)-0.3(PbTiO3)(001) heterostructure is studied using polarized neutron reflectometry, revealing changes in interfacial magnetism when a voltage is applied between the layers. For a better understanding of the results, structural characterization of the interfacial morphology is performed using transmission electron microscopy.
