Magnetoelectric composites (CoFe2O4)x-(BaTiO3)1?x with x = 0.1, 0.2, 0.3, 0.4 and 0.5 were prepared by a polyol mediated synthesis route. The densification step was performed in a reducing forming gas atmosphere at 1250 °C. Under these conditions Co2+ and Fe3+ are reduced to the corresponding metals and thus a reaction of these elements with the BaTiO3 matrix is prevented. Reoxidation in air to CoFe2O4 at a rather low temperature of 800 °C leads to samples free of secondary phases. While the course of the synthesis was monitored by TGA, XRD and photometric analysis, the final composites were characterized via SEM, EDX, impedance spectroscopy and magnetic and magnetoelectric (ME) measurements. All samples show pronounced ME hystereses and ?ME maxima dependent on the Hdc field sweep direction. The sample with x = 0.4 exhibits the highest maximum ?ME of 420 ?V Oe?1 cm?1.
