title = "M{\"o}ssbauer study of the effect of mechanical activation on the magnetic properties of PbFe0.5Nb0.5O3",
abstract = "M{\"o}ssbauer studies of PbFe0.5Nb0.5O3 samples prepared by mechanical activation of PbO, Fe2O3 and Nb2O5 mixture and subsequent sintering at various temperatures TS were performed. The room temperature M{\"o}ssbauer spectra consist of two doublets (D1 and D2) for the samples with TS < 800 °C and one doublet (D1) for the samples with TS > 800 °C. The parameters of the doublet D1 correspond to Fe3+ in the octahedron environment. Doublet D2 has a lower isomer shift corresponding to Fe3+ with the coordination number 5 that indicates the presence of oxygen vacancies. Dependence of the temperature TN of magnetic phase transition on TS has a maximum at TS ≈ 700 °C. The effect of Fe3+/Nb5+ ordering degree and oxygen deficiency on TN is discussed.",
