Pure barium titanate BaTiO_3 (BT) and BT doped with two different transition elements Fe^{3+} and Ni^{2+} at 5 mol.% (BT5Fe and BT5Ni, respectively) as constant concentration in powder form have been prepared by sol-gel method using barium acetate, titanium(IV) n-butoxide, iron and nickel nitrates as precursor materials. The microstructure of BT and the influence of Fe and Ni dopants on it were investigated...
In this paper the structural and Mössbauer spectral properties of multiferroic ceramic Bi_5Ti_3FeO_{15} powders prepared by high-energy ball milling of polycrystalline precursor material (mixture of Bi_2O_3, TiO_2 and Fe_2O_3 powders) are presented. Mechanical synthesis was performed by high-energy vibratory mill. The X-ray diffraction methods were applied for the structure characterization of the...
