Abstract
Dilute alloys of U in LaAl2 show low-temperature anomalies in both their normal state properties (susceptibility, thermopower) and superconducting properties (transition temperature, specific heat jump), which are phenomenologically related to the Kondo anomalies of Ce in LaAl2. This is the first observation of the Kondo effect in a dilute actinide alloy and demonstrates that in a favorable metallic host U-ions can carry localized magnetic moments.
