Multiferroic composites with general formula Ba(Ti0.95Zr0.05)O-3 - Ni0.7Zn0.3Fe2O4, Ba(Ti0.95Zr0.05)O-3 - CoFe2O4, Ba(Ti0.95Zr0.05)O-3 - Ni0.7Cu0.01Sm0.05Zn0.29Fe1.95O4, (BTZr(95-5) - NZF, BTZr(95-5) - CF, BTZr(95-5) - NCuSmZF) were prepared by mixing chemically obtained different types of ferrites and BTZ(95-5) powders in the planetary mill for 24 h. The optimization of sintering process was performed and powders were pressed and sintered at 1300 degrees C for obtained composites samples. From the X-ray analysis for single phase and composites ceramics the formation of crystallized structure of ferrites and barium zirconium titanate can be noticed. SEM analyses indicated the formation of two types nanosized grains, polygonal ferromagnetic and rounded ferroelectric grains. The electrical properties of these materials were investigated using impedance spectroscopy and analysis of ferroelectric measurements. Impedance analysis of all investigated samples has shown different relaxation pr...ocesses that originated from the grain and grain boundary contributions. The results of polarization vs. electric field measurements have shown the influence of magnetic phase type and its concentration on the ferroelectric properties of the composites. Due to high conductivity of ferrite phases and presence of interfacial polarization, the shapes of these curves differed from the conventional ferroelectric materials.
