Abstract

We report new experimental results on the pressure dependence of the superconducting transition temperature, T(c)(p), for the heavy-fermion superconductor CeCu2Si2. Two characteristic pressures, p1 = 3.0 GPa and p2 = 7.7 GPa, discriminate three regimes. A fairly linear decrease is observed in the intermediate regime. Data suggest that T(c) at zero pressure is strongly reduced relatively to this regime due to an unknown mechanism.
