摘要：
The results of the Mossbauer studies on Fe-57 nuclei in multiferroics BiFe1-x T (x) O-3 (T = Sc, Mn; x = 0, 0.05) in the temperature range of 5.2-300 K have been presented. The Mossbauer spectra have been analyzed in terms of the model of an incommensurate spatial spin-modulated structure of cycloid type. Information has been obtained about the effect of the substitution of Sc and Mn atoms for Fe atoms on the hyperfine parameters of the spectrum: the shift and the quadrupole shift of the Mossbauer line, the isotropic and anisotropic contributions to the hyperfine magnetic field, and also the parameter of anharmonicity of the spatial spin-modulated structure.
