We experimentally study a strain-meditated converse magnetoelectric (CME) effect in multiferroic heterostructures consisting of Co2MnSi and Pb(Mg1/3Nb2/3)O3-PbTiO3(PMN-PT). To investigate the CME effect, Co2MnSi films are grown on PMN-PT(001) at various growth temperatures by molecular beam epitaxy. Using magneto-optical Kerr-effect and strain measurements, we find that the remanent magnetization state only for the-ordered Co2MnSi/PMN-PT is modulated by the application of the lattice strain, while that for the-ordered Co2MnSi/PMN-PT is insensitive to the strain. We conclude that the formation of-ordered structure is needed to obtain an effective CME effect in the Co2MnSi/PMN-PT multiferroic heterostructure.
