The electrical resistivities of monoisotopic dilute alloys of Au- 171Yb and Au-174Yb have been measured down to 18 mK. A resistivity drop is observed in Au-171Yb, below 90 mK. This effect is shown to result from the magnetic hyperfine coupling in 171Yb which splits the electro-nuclear levels into a singlet ground state and a triplet excited state. A simple model is proposed which accounts for the experimental results.La résistivité électrique d'alliages dilués monoisotopiques d'Au- 171Yb et de Au-174Yb a été mesurée jusqu'à 18 mK. Dans l'Au-171Yb, on observe une chute de résistivité en dessous de 90 mK. On montre que cet effet résulte du couplage hyperfin magnétique dans l'171Yb qui lève la dégénérescence des niveaux électronucléaires en ...
