Antiferromagnetism and Superconductivity in CeRhIn${}_5$

Abstract

We discuss recent results on the heavy fermion superconductor CeRhIn${}_5$ which presents ideal conditions to study the strong coupling between the suppression of antiferromagnetic order and the appearance of unconventional superconductivity. The appearance of superconductivity as function of pressure is strongly connected to the suppression of the magnetic order. Under magnetic field, the re-entrance of magnetic order inside the superconducting state shows that antiferromagnetism nucleates in the vortex cores. The suppression of antiferromagnetism in CeRhIn${}_5$ by Sn doping is compared to that under hydrostatic pressure.
