A comprehensive study of the structural and magnetic properties of Ni1-xCrx (x= 10, 20) nanocrystalline alloys prepared by mechanical milling is reported in this paper.Abstract:
A comprehensive study of the structural and magnetic properties of Ni1-xCrx (x= 10, 20) nanocrystalline alloys prepared by mechanical milling are reported. From the structural and magnetic properties it is shown that the particles obtained after 30 hour milling are magnetically heterogeneous. High Curie temperature and weak magnetization values observed suggest that particles are in two phase structureor core shell structure.A comprehensive study of the structural and magnetic properties of Ni1-xCrx (x= 10, 20) nanocrystalline alloys prepared by mechanical milling are reported.

Magnetic properties of NiCr alloys
TL;DR: In this paper, the magnetization measurements on NiCr alloys were analyzed in terms of the itinerant band model of very weak ferromagnetism and several characteristic properties related to the effective exchange interaction and to the band structure near the Fermi level were deduced from this analysis.
