Herein we report on CoFeO/BiNaTiO–BaTiO biphasic ME composites, obtained by sol-gel chemistry, by mixing the precursor sols of the two phases into one precursor sol and further transforming it into gel, with the goal of obtaining homogeneous nanocomposites with magnetoelectric properties. The structural properties, the temperature dependance of dielectric properties, the magnetic and magnetoelectric properties of these biphasic mixtures, with various molar ratios CoFeO/BNT–BT = 0.5:1, 1:1 and 1.5:1, are investigated. It is observed that the amount of CoFeO and the synthesis in situ of these composites influences their macroscopic properties showing a high difficulty of carrying out an efficient poling resulting in small piezoelectric and magnetoelectric response. It was concluded that the synthesis procedure, the type of architecture and the interphase connectivity are of outmost importance for magnetoelectric properties based on lead-free materials.The authors gratefully acknowledge the financial support from Core Program PN19-0.3 (Contract No. 21N/08.02.2019) from the Romanian Ministry of Research.
