                      deposition. Thekey aspect of this study is to provide
                      accurate information about differences in electronic
                      andstructural properties in LSMO thin films as a function of
                      the oxygen pressure during BTO growth.X-ray absorption
                      spectroscopy experiments at the Mn L3,2 edge have revealed
                      the conservation ofMn3+/Mn4+ mixed valency configuration of
                      the LSMO films near the interface while tuning theoxygen
                      pressure of overlayer BTO growth. The existing Mn3+ ions
                      favor an in-plane eg orbitalordering, reducing the in-plane
                      strain and promoting room temperature ferromagntism in
                      theLSMO film. Furthermore, diffraction experiments showed
                      that the out-of plane lattice parameterof BTO reduces with
                      increasing oxygen pressure consistent with the x-ray linear
                      dichrosim at Tiedge showing less tetragonal symmetry,
                      although the chemical environment of the Ti ions was
                      notchanged notably. We demonstrated a way to control
                      magnetic properties and orbital ordering inLSMO thin films
                      while optimizing the ferroelectric properties of BTO
                      overlayer films, which arepromising results in terms of
                      magnetoelectric applications using functional
                      heterosystems.},
