Opis:: $0.5Bi_{0.95}Dy_{0.05}FeO_3-0.5Pb(Fe_{0.5}Nb_{0.5})O_3$ 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 $0.5Bi_{0.95}Dy_{0.05}FeO_3-0.5Pb(Fe_{0.5}Nb_{0.5})O_3$ 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.

Opis:: Pb-based complex perovskites with $Fe^{3+}$ like $Pb(Fe_{2//3}W_{1//3})O_3$ were found to be interesting because of their unique properties such as relaxor and magnetoelectric behavior. $Pb(Fe_{2//3}W_{1//3})O_3$ is ferroelectric with ferroelectric Curie temperature $T_{C}$ between 150 and 200 K and at the same time is antiferromagnetic with magnetic Néel temperature about 400 K. $BiFeO_3$ is a well known perovskite compound which exhibits ferroelectric ($T_{C}$ = 1103 K) and antiferromagnetic ($T_{N}$ = 643 K) ordering simultaneously. The polycrystalline sample of $0.3Bi_{0.95}Dy_{0.05}FeO_3-0.7Pb(Fe_{2//3}W_{1//3})O_3$ were synthesized using standard sintering procedure. Magnetization vs. magnetic field (at 4.2 K) curves were measured. Magnetoelectric properties of the sample were obtained.
