The voltage control of magnetism in oxide heterostructures has been extensively investigated for future spintronic devices. We grow single crystalline La0.67Sr0.33MnO3/BaTiO3 and La0.67Sr0.33MnO3/PMN-PT heterostructures by High Oxygen Pressure Sputtering System (HOPSS) and Oxide Molecular Beam Epitaxy (OMBE). Magnetometry measurements confirm the stability of the tetragonal phase of BaTiO3 down to 10K and the ferromagnetic state of La0.67Sr0.33MnO3. The manipulation of magnetization as a function of electric field will be studied with the combination of advanced scattering (neutron and X-ray) methods, electron microscopy and spectroscopy.
