Etude d'alliages granulaires Cu-Fe-Co : corrélation microstructure-comportements magnétiques-propriétés magnétorésistives
TL;DRAbstract
In 1992, the giant magnetoresistance effect was found in granular structures Cu-Co where metallic ferromagnetic particles are dispersed in a nonmagnetic metal matrix. It has been showed that this effect is very sensitive to the microstructure, particularly to the magnetic particle size, and to the distance between them. In the purpose to improve the understanding of the relationship between magnetoresistive properties and microstructure in granular compounds, the Cu80(Fe1-xCox) were elaborated by mechanical alloying, and study with different techniques. Each sample was structurally and magnetically characterized. The magnetoresistive properties were also studied. In the same way, granular ribbons Cu-SmCo5-Fe were investigated to characterize the influence of a hard magnetic phase on the magnetoresistive properties. All the results allow to correlate the microstructure and magnetic properties of the alloys to their magnetoresistive properties.
