Abstract

We investigated the electrical resistivity and heat capacity of 1% Cd-doped CeIrIn5 under hydrostatic pressure up to 2.7 GPa, near where long-range antiferromagnetic order is suppressed and bulk superconductivity suddenly reemerges. The pressure-induced Tc is close to that of pristine CeIrIn5 at 2.7 GPa, and no signatures of a quantum critical point under pressure support a local origin of the antiferromagnetic moments in Cd-CeIrIn5 at ambient pressure. Similarities between superconductors CeIrIn5 and CeCoIn5 in response to Cd substitutions suggest a common magnetic mechanism.
