Mössbauer study of the Al-Fe decagonal phase

Mössbauer spectroscopy has been used to get information about the atomic structure of the decagonal Al-Fe alloy. Mössbauer data distinctly support a structural model for the system which consists of a periodic stacking of two-dimensional Penrose lattices derived from the structure of the monoclinic ${\mathrm{Al}}_{13}$ ${\mathrm{Fe}}_4$ phase. Results of earlier Mössbauer measurements on similar systems are also discussed.
