      abstract     = {The demand for energy-efficient devices for future
                      technological applications is driving research in the field
                      of “voltage control of magnetism”. New developments in
                      oxide heterostructures offer great promise for improvements
                      in magnetic data storage, spintronics and high frequency
                      magnetic devices. Most current information storage devices
                      require high current densities to read or write information
                      in the form of local variations in magnetization. Since
                      correlated complex oxides possess strong coupling between
                      lattice, charge, spin and orbital degrees of freedom, they
                      offer the prospect of device concepts based on
                      magnetoelectric (ME) coupling. Here, I will talk about the
                      growth and characterization of epitaxial multiferroic
                      ferromagnetic/ (ferroelectric, piezoelectric)
                      heterostructures of
                      La0.67Sr0.33MnO3/0.7(Pb(Mg1/3Nb2/3)O3)-0.3(PbTiO3)(001):
                      LSMO/PMN-PT(001). Magnetic properties of LSMO/PMNPT (001)
                      heterostructure are studied using SQUID-VSM, which reveals a
                      clear existence of non-volatile ME coupling due to
                      asymmetric butterfly loop obtained on voltage application.
                      LSMO/PMNPT shows varying behavior of magnetoelectric
                      coupling as function of temperature which is observed
                      clearly in SQUID measurements. Using polarized neutron
                      reflectometry (PNR) magnetic depth profiles are probed as a
                      function of applied voltage. The interfacial morphology of
                      the heterostructure is characterized using transmission
                      electron microscopy, which agrees with PNR measurements
                      confirming the presence of an interlayer.},
