Abstract:
Magnetic properties of the La(Ni4.5M0.5), (La1-xRx)Ni5 (M = Fe, Co, Mn, Cu, Cr, Si and R =
Nd, Pr) and their hydride compounds have been studied by magnetization measurement using a VSM. The
susceptibility (??) of the samples increases with Co, Mn, Fe, Nd, Pr but decreases with Cu, Cr, Si additives.
The hydrogenation changes magnetic properties of the La(Ni4.5M0.5), (La1-xRx)Ni5 parent compounds.
Specially, the milling process changes magnetic properties of LaNi5. This work indicates that besides
electrochemical measurements, the study of magnetic properties also gives important information on the
quality of rechargeable sealed nickel-metal hydride batteries. ?? 2003 Published by Elsevier Science B.V.
