Résumé
Nous avons mesuré la résistivité électrique maximum dans Au Cu, (x = 5, 10, 15 et 20 at.%) avec 0,1 at. % impureté de Fe. Le maximum des alliages sont étudiés entre 2-4 K et montrent la coexistence des effets de Kondo et verres de spin dans les systèmes.
Abstract
We have measured the electrical resistivity maximum in Au1-x Cux (x = 5, 10, 15 and 20 at.%) with 0.1 at. % Fe impurities. This maximum lies between 2-4 K for the host alloys studied and indicates the coexistence of Kondo and spin glass effects in these systems.
