The (BaZrTiO₃)/(BaFeO); (BZT/BF) ( = 0, 0.1, 0.5 and 1 mol%) ceramics have been prepared via a solid state reaction process. Effects of BF content on the physical, microstructural, magnetic and electrical properties have been systematically investigated. High density sintered specimens (5.65-5.74 g/cm³) are obtained for all compositions. SEM micrographs show a decrease of grain size value when BF is added. Examination of the dielectric spectra show that the two phase-transition temperatures as observed for pure BZT, merges into a single phase-transition temperature for the added-samples. The addition of BF also improves the magnetic behavior ( hysteresis loops) of BZT ceramic and resultes in slight changes in ferroelectric properties. The maximum of remanent magnetization () of 7.19 emu/g is obtained for the 1 mol% sample.
