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.
