The use of converse magnetoelectric (ME) effect, i.e., voltage control of magnetization is one of the solutions towards reduction of power consumption in spintronic devices. Interfacial multiferroics (iMF) comprising a ferromagnet (FM) and a ferroelectric (FE) material are proved to be promising candidates rather than single phase multiferroics. A quantitative understanding is still required to offer a clear description of the mechanisms of the iMF coupling in a wide range of FM/FE heterostructures. In this work, we investigate the voltage induced ME response at the interface of Cu/Ni multilayer and (001) oriented [Pb(Mg_1/2Nb_2/3)O₃]_0.7-[PbTiO3]_0.3 (PMN-PT) substrate.
