Abstract

Systematic trends observed in the thermopower of heavy fermion compounds have led us to study CeCu2Ge2 under high pressure. As expected, the transport properties of this compound above 70 kbar were found to be quite similar to the normal pressure ones of CeCu2Si2. Around this pressure, magnetic ordering vanishes and superconductivity appears. At 101 kbar, the transition temperature Tc≈0.64 K and the critical field Bc2(0)≈2 T.
