Two Superconducting Phases in CeRh1-xIrxIn5
Abstract
Pressure studies of CeRh1-xIrxIn5 indicate two superconducting phases as a function of x, one with Tc >= 2 K for x < 0.9 and the other with Tc < 1.2 K for x > 0.9. The higher Tc phase, phase-1, emerges in proximity to an antiferromagnetic quantum-critical point; whereas, Cooper pairing in the lower Tc phase-2 is inferred to arise from fluctuations of a yet to be found magnetic state. The T-x-P phase diagram of CeRh1-xIrxIn5, though qualitatively similar, is distinctly different from that of CeCu2(Si1-xGex)2.
