The Zn–Sc–Fe icosahedral quasicrystal and its 1/1 crystal approximant have been studied with 57Fe Mössbauer spectroscopy at room temperature. The spectra for the two phases exhibit substantially different features, indicating largely different local atomic environments in the two phases. This is in contrast to the results previously reported for the Al–Cu–Fe(–Si) system, in which the icosahedral phase and its crystal approximants show similar features in Mössbauer spectra, indicating similar local atomic environments. Possible Fe sites in the Zn–Sc–Fe approximant phase are discussed on the basis of the crystal structure determined previously.
