      abstract     = {Magnetoelectric (ME) coupling in
                      La0.7Sr0.3MnO3/Pb(Mg1/3Nb2/3)0.7Ti0.3O3 (LSMO/PMN–PT
                      (001)) has been probed in the past years to identify the
                      underlying mechanism behind it. PMN–PT, which is well
                      known for its excellent piezoelectric properties, also
                      exhibits ferroelectricity. This motivates our interest to
                      differentiate which effect is dominant for this 'voltage
                      control of magnetism'. Here, we present results for the ME
                      coupling at different temperatures: 300 K and 80 K. In this
                      article we discuss and explain, how the nature of ME
                      coupling is influenced by different parameters such as
                      magnetic field, electric field, directional dependence (hard
                      axis, easy axis) and temperature. Owing to large lattice
                      mismatch between LSMO and PMN–PT, the strain-mediated
                      coupling is strongly prevalent, however the change in strain
                      behaviour from butterfly loop to linear loop is observed as
                      a function of temperature. ME measurements are performed
                      along hard axis [100] and easy axis [110] of LSMO in the
                      presence of remanent magnetic field which showcases the pure
                      influence of electric field on the system, resulting in a
                      combination of strain- and charge-mediated coupling. The
                      magnetic depth profile is probed by polarized neutron
                      reflectometry as a function of electric field which
                      demonstrates the existence of an interlayer with reduced
                      nuclear scattering length density and reduced magnetic
                      scattering length density at the interface. From
                      transmission electron microscopy, stoichiometric variations
                      are observed due to the presence of Mn3O4 particles at the
                      interface.},
