0.5Bi0.95Dy0.05FeO3-0.5Pb(Fe0.5Nb0.5)O3 is a multiferroic material which exhibits ferroelectric and antiferromagnetic ordering. (The synthesis of such compounds is rather difficult.) In this paper the way of the synthesis of 0.5Bi0.95Dy0.05FeO3- 0.5Pb(Fe0.5Nb0.5)O3 is presented. The detailed X-ray and Mössbauer effect studies were done and crystal and hyperfine interaction parameters were obtained. To measure electrical properties of the compound the impedance spectroscopy measurements were performed. The obtained impedance spectra were fitted using a proposed equivalent electrical circuit and the results were discussed in the scope of the brick layer model without easy paths.
