Hyperfine interactions and electrical properties of multiferroic 0.5Bi_0.95Dy_0.05FeO₃-0.5Pb(Fe_0.5Nb_0.5)O₃

0.5Bi_0.95Dy_0.05FeO₃-0.5Pb(Fe_0.5Nb_0.5)O₃ is a multiferroic material, simultaneously revealing ferroelectric and antiferromagnetic ordering, synthesis is rather difficult. In this paper we present a conventional solid state reaction method for synthesis of 0.5Bi_0.95Dy_0.05FeO₃-0.5Pb(Fe_0.5Nb_0.5)O₃ perovskite. A series of methodological measurements were carried out to determine the basic structural and electromagnetical properties. X-ray diffraction studies have been made in order to determine a crystal structure. Mössbauer effect spectroscopy was used to identify the oxidation state of Fe. Electrical properties of the perovskite ceramic were examined with impedance spectroscopy. The impedance spectra were analysed by means of an equivalent electrical circuit, and results are discussed in the scope of the brick layer model without easy paths.
