Structural analysis and 57Fe Mössbauer spectrometry of Zr6FeSn2 and related compounds

Hexagonal compounds of formula Zr6FeX2 were prepared and studied by X-ray and neutron diffraction and by 57Fe Mössbauer spectroscopy. The first results indicate that most of the compounds can be prepared mainly as a single phase after at least 5 weeks of annealing at a temperature close to 900 °C. In particular, the hyperfine parameter distributions in Mössbauer spectra reflect the ability to form pure phases.
