Abstract Compounds with the composition R6Fe13X (R=Pr, Nd; X=In, Sn, Tl, Pb, Cu, Ag, Au) were studied by57Fe Mössbauer spectroscopy. Attention was focused on the influence of the easy axis of the magnetization on the shape of the hyperfine patterns. The spectra are composed of at least four subpatterns, originating from the different Fe lattice sites. Contrary to the magnetization, a significant dependence of the hyperfine parameters on the specific elements R and X could not be detected. Predominantly, the easy axis of the magnetization was found to lie within the basal plane; only for R=Nd and X=In, Sn, Tl, Pb is an easyc-axis present. Since the low temperature magnetization data obtained for the different compounds show a wide spread, while the57Fe hyperfine fields remain almost constant over the whole series, some kind of antiferromagnetic ordering within the Fe sublattice is anticipated.
