| Abstract: | The remarkable
modification in physical and magnetic properties of ternary Ni, Cu and Al based
ensemble of ball milled nanoparticle alloys and their crystalline shape with
grain size and composition has been studied in the present paper. The onset of
crystalline changes have been correlated to grain size and alloying content. A
sharp decrease in ferromagnetism maintaining the cubic symmetry with grain size
and alloying was also revealed. These alloys show two phase transitions, one
near room temperature and the other near 80°C compared to 200°C for
similar bulk compositions. Such observations have been explained and their
possible usage is being explored.
