✦ Synopsis

CeCusSis single crystals (Tc : 0.63-0.68 K) have been studied utilizing calorimetric, dilatometric and ultrasound experiments. The strain dependencies of Tc along the a-and c-axis have opposite sign and indicate that superconductivity is favoured upon compensatron of the local 4f moments. According to the crr(T,B) behaviour, T, appears limited by an additional, presumably antiferromagnetic, instability of the Fermi liquid.
