摘要：

From high pressure transport measurements we compare the normal and superconducting properties of CeCu2Ge2 and CeCu2Si2. The pressure-induced enhancement of the superconducting transition temperature T-c up to about 2 K is correlated to several characteristics of the normal phase which all point to the possibility that charge fluctuations are involved in superconductivity. We also examine whether the transport properties of CeRu2Ge2 and YbCu2Si2 show deviation of the Fermi liquid behaviour in the vicinity of the magnetic to non-magnetic transition.
