Multiferroic　ceramics　Bi0.8Ba0.2Fe1-xTixO3　with　x　=　0,　0.1　and　0.2　were　prepared　by　using　the　conventional　solid　state　reaction　method.　The　structural,　dielectric,　ferroelectric　and　magnetic　properties　were　investigated.　The　structure　phase　transition　from　rhombohedral　to　tetragonal　with　increasing　the　Ti　substitution　concentration　was　confirmed　using　X-ray　diffraction.　The　reduction　of　low　frequency　dispersion　in　the　dielectric　constant　and　loss　with　an　increase　in　the　Ti　content　was　observed.　The　ferroelectric　measurements　revealed　that　the　leakage　current　is　significantly　suppressed　with　Ti　substitution.　Magnetic　hysteresis　loops　showed　a　continuous　decrease　in　magnetization　with　Ti　substitution,　which　can　be　attributed　to　the　collinear　antiferromagnetic　spin　structure　in　tetragonal　structure.　In　addition,　a　remarkable　change　in　the　polarization　and　ferroelectric　loop　area　after　poling　the　samples　in　the　dc　magnetic　field　indicates　the　presence　of　magnetoelectric　coupling　at　room　temperature.　(C)　2013　Elsevier　B.V.　All　rights　reserved.
