Opis:: Multiferroic 0.5BiFeO3-0.5Pb(Fe0.5Ta0.5)O3 solid solution is a material that exhibits ferroelectric and antiferromagnetic orderings in ambient temperature. The solid solution was obtained as a result of a conventional reaction in a solid state. The obtained material is a dense, fine-grained sinter whose surface was observed by scanning electron microscopy (SEM) and stoichiometry was confirmed by energy dispersive X-ray spectroscopic (EDS) analysis. According to the X-ray powder diffraction (XRD) measurements, the main phase is R3c space group with admixture of Pm-3m regular phase. Small contribution of pyrochlore-like phase was also observed. Mössbauer spectroscopy suggested random distribution of Fe3+/Ta5+ cations in the B sites of ABO3 compound. Reduction of the magnetic hyperfine field with an increase in the substitution of Ta5+ in Fe3+ neighbourhood was also observed.

Opis:: A polycrystalline ceramic of $0.5Bi_{0.95}Dy_{0.05}FeO_{3}-$ $0.5Pb(Fe_{2//3}W_{1//3})O_{3}$ was synthesized from a solid-state reaction method. At room temperature material exhibits both magnetic and electric dipolar properties simultaneously. Detailed X-ray diffraction analysis and Mössbauer effect studies have been done to determine the crystallographic structure and magnetic properties of $0.5Bi_{0.95}Dy_{0.05}FeO_{3}-$ $0.5Pb(Fe_{2//3}W_{1//3})O_{3}$. $T_{N}$ temperature was estimated at around 600 K.

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.
