INFLUENCE OF DEPOSITION CURRENT-DENSITY ON THE MAGNETIZATION BEHAVIORIN ELECTRODEPOSITED NI-MN ALLOYS

Ni-Mn alloys were electrodeposited at different current densities from sulphate baths and their magnetization behaviours at different fields were studied. The magnetization decreases with increase in deposition CD in the absence of additives. The magnetization behaviour of Ni-Mn is different from that of its counterpart i.e. the electrodeposited Fe -Mn system The system is free from pronounced ferromagnetic coupling b etween Mn spins. The magnetic moments in high field regions are heavil y influenced by the presence of Mn spins.
