Abstract
Mossbauer measurements on Ni-Mn alloys with 25.5 and 33 at.% Mn have been carried out and analysed using some of the concepts used in an earlier study of Ni-Mn alloys with smaller Mn concentration by Ray et al. (1974). The spectra have been explained by a distribution of hyperfine fields arising from Fe atoms located in different nearest-neighbour environments. The value of these hyperfine fields is related to their corresponding Fe exchange fields in these environments. It is found that an Fe atom occupying Mn sites shows a stronger temperature dependence of hyperfine field than those occupying Ni sites. The nature of the Fe moments in these alloys is also discussed.Keywords
