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 T_c≈0.64 K and the critical field B_c2(0)≈2 T.
