Structure and Electromagnetic Properties of Bi1-xYxFe0.95Mn0.05O3 (x=0.05, 0.075 and 0.10)

The effect of Y and Mn co-doping on the structural and electromagnetic properties of BiFeO3 is described. Multiferroic ceramics of Bi1-xYxFe0.95Mn0.05O3 (x = 0.05, 0.075 and 0.10) have been synthesized by the sol-gel method. Phase, structure and microstructure analyses were performed by scanning electron microscopy and X-ray diffraction followed by Rietveld analysis. Y saturation and consequent formation of a secondary phase was observed. Electric and magnetic measurements show that investigated doping is beneficial. Dielectric loses decreases, ferroelectric and ferromagnetic loops compare favorably with those corresponding with competing compositions.
