AB  - Polycrystalline Bi1-xPr(Ce)(x)FeO3 ceramics (x = 0, 0.03, 0.05 and 0.10) were prepared by auto-combustion method using urea as a fuel. The influence of Pr(Ce) doping on structural, vibrational, morphological, dielectric and ferroelectric properties of BiFeO3 polycrystalline ceramics was investigated. From X-ray diffraction (XRD) and scanning electron microscopy measurements it was observed that Pr(Ce) doping generated a reduction of the crystallite (grain) size of BiFeO3 and contraction of the rhombohedral cell due to the increased compressive strain. The changes seen in the XRD and Raman spectra of 10% Pr(Ce)doped samples, pointed to a probable appearance of orthorhombic (pseudotetragonal) crystal structure. The pristine BiFeO3 exhibited rounded shape, non-saturated ferroelectric hysteresis loop. The dielectric constant and dielectric loss have shown strong dispersion at lower frequencies, typical for conductive BiFeO3. Dielectric and ferroelectric properties at room temperature were improved with Pr doping. Concerning the Ce-doped samples, only the 3% Ce-doped sample exhibited a better shaped hysteresis loop and improved dielectric properties compared to the pristine BiFeO3. With further increase of Ce content the ferroelectric properties degraded.

AB  - Nanosized nickel zinc ferrite powders with general formula Ni1-xZnxFe2O4 (x=0.0, 0.3, 0.5, 0.7, 1.0) were synthesized by an auto-combustion method starting from metal nitrates. X-ray analysis indicated the formation of well crystallized Ni-Zn ferrite phases, and Raman spectroscopy enabled a precise phases identification. The change of the grain size and density with increasing Zn content was confirmed by scanning electron microscopy. Magnetization of saturation and remnant magnetization, both, continuously increase up to x=0.3 of Zn, and then decrease for more Zn. The influence of the grain size of investigated systems on the saturation magnetization was studied. Impedance spectroscopy measurements were carried out in order to investigate the electrical resistivity of materials, showing that grain boundaries have greater impact on total resistivity that grains.
