AB  - Bismuth ferrite (BiFeO3) is considered one of the most promising single phase multiferroic materials thanks to the fact it exhibits ferroelectric and antiferromagnetic properties in the same time in very wide range of temperatures (up to 370 °C). Difficulties in obtaining pure BiFeO3 phase and dense ceramics, together with occurrence of leakage currents have prevented application of BiFeO3.
Substitution of Bi3+ or Fe3+ ions with some transition metal or rare earth ions can
improve both electrical and magnetic properties by reducing leakage currents and introducing weak ferromagnetism through structural changes.
Y doped bismuth ferrite, Bi1-xYxFeO3, was synthesized by auto-combustion method using urea as a fuel. Precursor powders were annealed, pressed and sintered. Powders and ceramic samples were characterized by XRD, SEM, Raman, impedance spectroscopy, ferroelectric and magneticmeasurements.
X-ray diffractograms and Raman spectra showed no presence of secondary phases. SEM images indicated lowering of grain size with higher concentration of Y3+. Electrical resistance is highly improved even at 1 % of Y, while 10 % of Y was necessary to break spiral spin structure, leading to weak ferromagnetism.

AB  - NiZnFe2O4 (NZF) powder was prepared by auto-combustion method starting from nickel, zinc and iron nitrates. Thermal treatment was performed at 1000 oC for 1 h after which the nickel ferrite powder was formed. Barium titanate (BT) powder was prepared with same method using titanyl nitrate and barium nitrate as a starting reagents. Multiferroic composites with formula BaTiO3– Ni(1-x)ZnxFe2O4 (x = 0.3,
0.5, 0.7) were prepared by mixing chemically obtained NZF and BT powders in the planetary mill for 24 h. Powders were pressed and sintered at 1170 oC for 4 h. Samples were characterized by XRD, Raman, SEM, IR. Magnetic and electrical measurements were also carried out. X-ray and Raman measurements confirmed the
presence of NZF, BT phases and the traces of barium ferrite phase. The microstructure of the ceramics shows (Fig. 1.) the formation of polygonal (NZF grains), rounded (BT grains) and plate like grains (barium ferrite phase). The impedance analyses of multifferoic composites at 200 ºC have shown the contribution of both, grain and grain boundary resistivity.
