Abstract Evidence is presented, based on analyses of57Fe Mössbauer spectra of magnetically ordered Al−Cu(Fe)−Ge−Mn icosahedral alloys measured at 4.2 K, for the dependence of Fe substitution upon the concentration of Fe. It is found that Fe substitutes approximately randomly on transition-metal (TM) sites, i.e., it enters both magnetic and nonmagnetic class of sites, for very small concentration of Fe. However, for larger concentration, Fe enters preferentially the nonmagnetic class of sites. This is discussed in terms of recent theoretical calculations which predict the dependence of a magnetic moment of a TM atom upon the volume associated with it in an alloy.
