BaTiO3 powders doped with Ag at different Ag/Ba molar ratios were prepared by sol-gel method. The resistivity reached the lowest point of 5.644 Ω·m when Ag concentration was 0.10 at% and the powders were calcined for two times at 800°C and 500°C. XRD and FTIR investigations showed that no new substance was formed after the doping and calcining process, but the particle size and the strength of Ti-O bond in modified BaTiO3 crystal cell all changed. The conductivity of Ag-doped BaTiO3 powders with different Ag concentrations and through different preparing methods was discussed by using defect theory.

Abstract: Nanocomposite particles SrFe12O19/ CoFe2O4 were synthesized by sol-gel method. The nanocomposites are formed at the calcining temperature around 850 oC in 5 hours. The phase composition, surface morphology and magnetic properties of the nanocomposites were investigated using XRD, SEM and VSM, respectively. The results show that the magnetic properties of nanocomposite particles are strongly influenced by the molar ratios of the hard and soft phases and particle size distributions. The samples with the mass ratio of Rm= SrFe12O19/ NiFe2O4 = 1/3 and 1/5 are characterized with a “bee waist” type hysteresis loop. While all the samples RV show an excellent smooth hysteresis loop and a single – phase magnetization behavior. The coercivity decreases significantly and the magnetization drastically increases with decreasing of volume ratio RV. Keywords: nanocomposite, sol- gel method, exchange coupling.
