Abstract
The evolution of giant magnetoresistance (GMR) of rapidly quenched Cu85Co15 and Cu80Co20 ribbons has been studied on samples after selected thermal tr eatment. The observed changes were correlated with the results from structu ral analysis by X-ray diffraction and transmission electron microscopy (TEM ) and electron diffraction analyses. The results indicate spinodal decompos iton of the supersaturated Cu-Co alloy with Co precipitating into distinct Co-ggregates.
