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.
