Multiferroic BiFeO 3 has attracted extensive interest due to its potential in several applications. However, pure-phase BiFeO 3 is very difficult to obtain. Hence, mixing BiFeO 3 with other ferroelectrics, such as BaTiO 3 , is another approach to obtain materials with possible multiferroic properties. In this study, the BiFeO 3 was modified with addition of BaTiO 3 via a simple solid state reaction method. Dielectric properties of the BaTiO 3 -modified BiFeO 3 ceramics were investigated over wide range of temperature and frequency. The results show that the (1-x)BiFeO 3 -xBaTiO 3 ceramics with x = 0.1 and 0.2 exhibited large dielectric properties with giant-dielectric-like behavior. The dielectric properties were seen to improve with increasing BaTiO 3 content, with the highest dielectric constant (ε r = 19000) observed in 0.8BiFeO 3 -0.2BaTiO 3 ceramic. The results were explained in terms of the pre-dominantly intrinsic BiFeO 3 giant-dielectric behavior as a result of Fe multivalent states, as well as a better grain packing density with increasing BaTiO 3 content. © Taylor & Francis Group, LLC.
