摘要：
Pressure studies of CeRh1-xIrxIn5 indicate two superconducting phases as a function of x, one with T(c)greater than or equal to2 K for x<0.9 and the other with T-c<1.2 K for x>0.9. The higher T-c phase, phase 1, emerges in proximity to an antiferromagnetic quantum-critical point; whereas, Cooper pairing in the lower T-c 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).
