Magnetism and Superconductivity in CeRhIn5

Understand

We give a review of recent results on the heavy fermion superconductor CeRhIn$_5$ which presents ideal conditions to study the interplay of antiferromagnetism and superconductivity.

• The main results are the appearance of domains of microscopic coexistence of antiferromagnetism and superconductivity under both, pressure and magnetic field scans.
• At zero magnetic field, under pressure coexistence appears from the onset of pressure induced superconductivity up to the critical pressure $p_c^\star$ where antiferrmognetism disappears abruptly.
• Under magnetic field, re-entrance of magnetic order inside the superconducting state occurs in the pressure range from $p_c^\star$ up to $p_c$.
