Mössbauer investigations of the metastable Fe23B6 phase

Mössbauer spectroscopy was used to study hyperfine interactions in the metastable phase Fe 23 B 6 that was for the first time obtained in macroscopic amounts in an almost single-phase state. Parameters of 57 Fe(300 K) spectra, as well as local and average magnetic moments at iron atoms have been calculated. It is indicated that the specific features of Mössbauer spectra and hyperfine-field distributions P ( H ) in mechanically synthesized Fe 23 B 6 compounds are determined by the modification of the parameters of local surroundings of Fe atoms in positions 48 h and 32 f of the unit cell.
