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 measurements and mu (+)SR spectroscopy results are in good agreement with a systematic Fe-57 Mossbauer spectroscopy analysis. The strength of all local iron magnetic moments (and the related hyperfine fields), as well as the long range magnetic ordering, have been found to be markedly affected by the substitution of iron by molybdenum in Fe(8i) sites. It was found that the temperature dependence of the order/disorder phenomenology is well described by local magnetic correlation.
