Abstract
Ni3Fe alloy with different grain sizes has been formed by mechanical alloying technique using a high energy ball mill. 57Fe Mِssbauer studies have been carried out at room temperature and hyperfine field distributions have been obtained for various milling durations. The influence of surface atoms on magnetic hyperfine fields and the effect of grain size on Fe magnetic moment have been investigated. The atomic ordering is found to be faster in the nanocrystalline form of Ni3Fe than in the bulk Ni3Fe.
