Abstract
We present ESR-data for Gd3+-impurities in the heavy fermion compound CeAl3 under hydrostatic pressure up to 17kbar. At ambient pressure andT<4K the Gd-resonance shows a strongly enhanced thermal broadening with respect to isostructural LaAl3. With increasing pressure this slope decreases from at least 138 Oe/K (p=0) to 18 Oe/K (p=17kbar) which is almost the Korringa slope of LaAl3. These results support the idea of an increasing Ce-spin fluctuation rate as a function of pressure.
