Observation of two distinct superconducting phases in Ce[Cu.sub.2][Si.sub.2]

We report the presence of two disconnected superconducting domes in the pressure-temperature phase diagram of partially germanium-substituted Ce[Cu.sub.2][Si.sub.2]. The lower density superconducting dome lies on the threshold of antiferromagnetic order, indicating magnetically mediated pairing, whe...
