Abstract
A series of RFe(12-x)M(x)-type alloys were stabilised with M = Mo and x = 2.5 for R = Y, Nd, Dy and Er. Magnetisation, ac susceptibility mea surements and mu (+)SR spectroscopy results are in good agreement with a systematic Fe-57 Mossbauer spectroscopy analysis. The strength of a ll local iron magnetic moments (and the related hyperfine fields), as well as the long range magnetic ordering, have been found to be marked ly affected by the substitution of iron by molybdenum in Fe(8i) sites. It was found that the temperature dependence of the order/disorder ph enomenology is well described by local magnetic correlation.
