PREPARATION OF FE-CO-P AMORPHOUS-ALLOYS BY ELECTRODEPOSITION

Different series of samples containing Fe, Co and P have been obtained by electrodeposition. They have been prepared with different plating parameters such as bath composition, working electrode voltage (versus reference), and nature of counter-electrode. The influence of those v ariables on the composition and properties of the deposit is investiga ted and discussed, in comparison with the binary alloys Fe-P and Co-P. In all the cases, increasing the voltage increases the content of Fe, while the proportion of Co and P decrease. Samples with less that 10 at.% P are partially crystalline. All the samples are ferromagnetic at room temperature and their hysteresis loops show different shapes dep ending on the relative content of Fe and Co.
