      abstract     = {In this article we report on the synthesis and multiferroic
                      properties of cobalt ferrite (CoFe2O4)–barium titanate
                      (BaTiO3) biphasic composites. The initial composite
                      nanopowder was synthesized by a combination of
                      co-precipitation and organosol methods. A ceramic sample
                      with (3–0) connectivity, i.e. BaTiO3 grains in a CoFe2O4
                      matrix was obtained by a combination of spark plasma
                      sintering and annealing. In order to understand the
                      correlations between morphology, electric properties, and
                      magnetization, we present a detailed study at different
                      preparation steps and compare it to the properties of a
                      conventionally sintered sample with the traditional (0–3)
                      connectivity, i.e. CoFe2O4 grains in a BaTiO3 matrix. We
                      observe that the (3–0) sample shows improved magnetic
                      properties in comparison to the conventionally sintered
                      composite of the same composition. In spite of relatively
                      large leakage current for the (3–0) sample compared to the
                      traditional (0–3) one, it exhibits a converse
                      magnetoelectric effect that follows the Hdc dependence of
                      the piezomagnetic coefficient. The magnetic field-dependence
                      of electric polarization at the surface was investigated
                      utilizing X-ray absorption spectroscopy and its associated
                      linear and circular dichroisms.},
