Abstract

Mössbauer 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 Mössbauer 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.
