Abstract
Electrodeposition of Ni-Fe without or with superimposition of magnetic induction has been performed. An intensity-potential curve evolution under moderate magnetic field and electrochemical impedance spectroscopy measurements has made evident the deposition according the Matlosz model. In our case, the magnetic field enhanced the iron adsorption phenomenon. The magnetic susceptibility of the obtained deposits has been studied and a break of this susceptibility appeared for a composition value close to that of the Invar\textregistered (Ni36Fe64). The magnetic field impact on the susceptibility values shows some evolutions imputed to morphology modification. Figs 8, Refs 9.
