AbstractIron-cobalt alloy and cobalt-magnetite composites doped with Nd3+ (CoxFe1-x/Coy Fe1-yNdzFe2-zO4) in which the Fe alloy has either a bcc or a fcc structure and the oxide is a spinel phase, have been synthesized by using the disproportionation of Fe(OH)2 and the reduction of Co(II) by Fe0 in a concentrated KOH solution. Powder X-ray diffraction, scanning electron microscope and vibrating sample magnetometer were employed to characterize the crystallite sizes, structure, morphology and magnetic properties of the composites. And the effect of the Co(II)/Fe(II) ratio (0 ≤ Co/Fe ≤ 1), concentration of KOH, reaction time and substitution Fe3+ ions by Nd3+ ions on structure, magnetic properties of the composites were investigated. From the perspective of thermodynamics, we explain the postulated mechanism of the disproportionation reaction. © Springer Science+Business Media, LLC 2009.
