Abstract
We report measurements of the pressure-dependent superconducting transition temperature T-c and electrical resistivity of the heavy-fermion compound C eCoIn5. Pressure moves CeCoIn5 away from its proximity to a quantum-critica l point at atmospheric pressure. Experimental results are qualitatively con sistent with theoretical predictions for strong-coupled, d-wave superconduc tivity in an anisotropic three-dimensional superconductor.
