Non-linear effect of uniaxial pressure on superconductivity in CeCoIn5
arXiv:1010.4653 · doi:10.1103/PhysRevB.83.144510
Abstract
We study single-crystal CeCoIn5 with uniaxial pressure up to 3.97 kbar applied along the c-axis. We find a non-linear dependence of the superconducting transition temperature Tc on pressure, with a maximum close to 2 kbar. The transition also broadens significantly as pressure increases. We discuss the temperature dependence in terms of the general trend that Tc decreases in anisotropic heavy-fermion compounds as they move towards three-dimensional behavior.
