 Abstract: Measurements of the thermal expansion, α(T), between 0.05 and 370 K are reported for the Kondo system CexLa1−xAl2 with 0.07 ⩽ x ⩽ 1. As the most intriguing result we find for all samples a negative α(T) anomaly at sufficiently low temperatures. Our data suggest this anomaly to be a single-ion property. A natural explanation is furnished by a local Fermi-liquid picture.
