Resumo

The 57Fe NMR spectra and relaxation times in θ-Fe3C cementite in the region of long-range magnetic order were obtained and analyzed. The values of hyperfine magnetic fields for two nonequivalent positions of iron atoms in the structure (Pnma) of this compound and their evolution in the temperature range from 4.2 to 350 K were determined. From the analysis of the 57Fe Mossbauer spectra obtained at T = 295 K, the components of the electric field gradient tensor and the values of hyperfine fields were determined.
