| 520 | _ | _ | |a 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. |
