Abstract

We have prepared mechanically alloyed samples of FeNi, FeNi3, and (FeNi3)1 − xAgx. The production of nanometer size grains was confirmed by x-ray broadening and electron microscopy. X-ray measurements indicated that a small amount (~7%) of Ag could be alloyed into the Fe-Ni and that considerable lattice strain was present. Mössbauer and magnetic measurements found no evidence for superparamagnetism in these alloys.
