We show giant converse magnetoelectric effect in a multiferroic heterostructure consisting of ferromagnetic Heusler alloy Co2FeSi and ferroelectric-oxide Pb(Mg1/3Nb2/3)O3-PbTiO3 for an electric-field control of magnetization vectors. In this system, the non-volatile and repeatable magnetization vector switchings in remanent states are also demonstrated. This approach can lead to a new solution to the reduction in the write power in spintronic memory architectures at room temperature.
