Abstract: Conventional solid-state reaction method has been employed for the synthesis of polycrystalline (Bi0.9Gd0.1FeO)1-x (BaTiO3) x for x=0.1, 0.2 and 0.3, ceramics samples. The effect of BaTiO3 content on the multiferroic properties of Gd-doped BiFeO3 ceramics has been presented. Pure perovskite phase with high density has been obtained by optimizing the synthesis approach, calcination and sintering strategies. Structural analysis carried out using X-ray diffraction confirms the formation of desired morphotropic phase. The dielectric properties have been investigated at different concentration of BaTiO3 as function of temperature, revealing that by increasing the BaTiO3 content dielectric constant increases while dielectric losses decrease. Magnetic study shows that initially saturation magnetization increases with increase in BaTiO3 content up to x=0.1; however, afterwards it decreases for higher concentration of BaTiO3. According to ferroelectric measurements, PE loops (with low coercive field) are observed at room temperature. The remnant polarization (P r ) has been found to be 0.169, 0.619 and 0.760 μC/cm2, respectively, for samples with x=0.1, 0.2 and 0.3. Magnetoelectric coupling in as-synthesized samples has been indirectly deduced by an anomaly observed at magnetic transition temperature. © 2013 Springer Science+Business Media New York.
