Superconductivity and Quantum Criticality in CeCoIn_5
arXiv:cond-mat/0202251 · doi:10.1103/PhysRevLett.89.157004
Abstract
Electrical resistivity measurements on a single crystal of the heavy-fermion superconductor CeCoIn_5 at pressures to 4.2 GPa reveal a strong crossover in transport properties near P^* \approx 1.6 GPa, where T_c is a maximum. The temperature-pressure phase diagram constructed from these data provides a natural connection to cuprate physics, including the possible existence of a pseudogap.
