Abstract
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 resultsKeywords
