Bi0.90Ba0.10Fe0.90Ti0.10O3 and Bi0.90Ba0.10Fe0.88Cr0.02Ti0.10O3 multiferroic ceramic systems were prepared, by using conventional solid-state reaction method from oxides and carbonates, in order to evaluate the chrome influence on physical properties of the Ba2+ and Ti4+ co-doped BiFeO3 (BFO). The structural analysis was carried out by using X-ray diffraction and Scanning Electronic Microscopy at room temperature. A rombohedral perovskite structure has been evaluated for both compositions. The dielectric analysis was carried out in a wide temperature and frequency ranges. The results have showed a clear magneto-electric coupling; the Cr3+ ions play also an important role decreasing the electrical conductivity of the studied multiferroic compositions. The doping element has also showed an important influence on the characteristic magnetic hysteresis, which has been evaluated at room temperature.
