Nuclear quadrupolar resonance measurements find that, under hydrostatic or chemical pressure, the heavy fermion antiferromagnet CeRhIn5 becomes more itinerant and the Neel temperature TN increases slightly at low pressures but decreases at large pressures. In CeRh0.5Ir0.5In 5, unconventional superconductivity sets in well below T N, with enhanced Tc ≈ 1 K.
