Abstract
Among REBe(13) intermetallic compounds, YbBe13 is anomalous, with evid ence for mixed-valence and heavy-fermion behaviour. The comparatively low specific resistivity and, therefore, the large electronic mean fre e path enables point-contact spectroscopy in the Sharvin regime. In th e d(2)V/dI(2) characteristics of point-contacts between YbBe13 and nor mal metals, measured at temperatures between 1.6 and 30K, we find stru ctures due to crystal-field scattering and scattering at spin-fluctuat ions.
