Abstract

Sm2Fe17−x Si x (x ≤ 2) prepared by mechanical alloying and subsequent annealing. They are single phase with the R3m Th2Zn17-type structure. The best Rietveld agreement factor assesses for a preferential occupation of Si on the 18h site. These results are corroborated by the Mössbauer spectroscopy measurements obtained from 295K down to 77K. The Mössbauer spectra analysis is based on the correlation between the Wigner-Seitz volume and the isomer shift evolution taking into account the statistical distribution of Si in the 18h site.
