摘要：

The results of a M & ouml;ssbauer study of hyperfine interactions of Fe-57 probe nuclei in isostructural hexagonal manganites h-ScMnO3 and h-InMnO3 are presented. The results of measurements of the M & ouml;ssbauer spectra at T > T-N, as well as calculations of the parameters of the electric field gradient tensor at Fe-57 nuclei, demonstrated different behavior of the probe iron ions in these isostructural systems, reflecting the difference in the processes of defect formation in their crystal lattices. On the contrary, measurements at T < T-N did not reveal any differences in the local magnetic structure of Fe-57 probe atoms in these oxides.
