Opis:: The complex perovskite system xźBi0.95Dy0.05FeO3-(1 - x)źPb(Fe2/3W1/3)O3 was synthesized by the solid-state reaction method and was studied by means of Mössbauer spectroscopy. For different Dy-doped bismuth ferrite (BDF) contents (x = 0.1, 0.3, 0.5, 0.7) the formation of single-phase sinters was confirmed using an X-ray diffraction technique. The random distributions of Fe/W cations in crystallographic structures have been proved. A monotonically, saturation- like increase of Néel temperatures with growing BDF contribution was confirmed, and a straightforward dependence between TN temperatures and the mean hyperfine magnetic fields at Fe nuclei was shown.

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:: This paper concerns the synthesis of yttrium-dilute Tb0.27-xYxDy0.73Fe2 intermetallic series with a borderline compound Tb0.27Dy0.73Fe2 known as Terfenol-D by arc melting, XRD analysis and 57Fe Mössbauer effect studies at 295 K. XRD analysis (295 K) shows that all samples crystallize in a cubic, Fd3m, MgCu2-type structure. The lattice parameter increases along with yttrium content. Mössbauer effect spectra for the Tb0.27-xYxDy0.73Fe2 series collected at 295 K consist of two subspectra due to easy direction of magnetization <111>. Hyperfine interaction parameters: isomer shift, magnetic hyperfine field and a quadrupole splitting were obtained from the fitting procedure of the spectra.

Opis:: 57Fe Mössbauer effect studies were performed for the cubic C15, Fd3m, MgCu2-type Dy(Co0.4-xNixFe0.6)2 intermetallics. Hyperfine interaction parameters : isomer shift, magnetic hyperfine field and quadrupole interaction parameter were obtained from the fitting procedure of the collected 57Fe Mössbauer effect spectra. As a result of Co/Ni substitution, a Slater-Pauling type curve for the average magnetic hyperfine field vs. Ni content in the Dy(Co0.4-xNixFe0.6)2 series is observed.
