Abstract

We report measurements of the pressure-dependent superconducting transition temperature T c and electrical resistivity of the heavy-fermion compound CeCoIn 5 . Pressure moves CeCoIn 5 away from its proximity to a quantum-critical point at atmospheric pressure. Experimental results are qualitatively consistent with theoretical predictions for strong-coupled, d-wave superconductivity in an anisotropic three-dimensional superconductor.
