A Mössbauer Effect Study of Y2Fe17 and Y2Fe17N2.6
The Mössbauer effect spectra of Y2Fe17 and Y2Fe17N2.6, obtained at 85 K, are analyzed with a model consistent with their crystallographic structures and band structure calculations of their magnetic moments. The increases in the individual site isomer shifts and hyperfine fields upon nitrogenation correlate well with the increases in both the individual Wigner-Seitz cell volumes and the magnetic moments. The spectral analysis, which requires ten sextets, indicates that the magnetization lies in a general direction in the hexagonal basal plane of these compounds.
