(1-x)BaTiO3-x(Na1/4Bi3/4)(Mg1/4Ti3/4)O-3　(0　＜　x　＜=　0.2)　ceramics　were　synthesized　by　the　solid-state　reaction　and　verified　to　form　the　perovskite　structure.　Three　dielectric　anomalies　corresponding　to　the　three　phase　transitions　of　BaTiO3　were　observed　for　samples　with　0.1　＜=　x　＜　0.2　and　one　of　those　dielectric　anomalies　exhibit　relaxation　behavior.　At　x　=　0.2,　three　phase　transitions　are　pinched,　and　a　distinct　ferroelectric　relaxor-like　behavior　dominates.　Hysteresis　loops　were　observed　for　the　compositions　with　0　＜　x　＜=　0.2.　For　0.14　＜=　x　＜　0.2　partial　linear　P-E　behaviors　are　observed.　Coexistence　of　pseudo-cubic　(Na1/4Bi3/4)(Mg1/4Ti3/4)O-3　and　rhombohedral　BaTiO3　phases　depict　a　typical　relaxor　behavior　in　this　system.
