Abstract

We report a thermodynamic and transport study of the phase diagram of CeRh1-xIrxIn5. Bulk superconductivity is observed over a broad range of doping, 0.3<x<~1, including a substantial range (0.3<x<0.6) over which it coexists with magnetic order (which is observed for 0<~x<0.6). The anomalous transition to zero resistance that is observed in CeIrIn5 is robust against Rh substitution: the bulk Tc in CeRh0.5Ir0.5In5 is more than double that of CeIrIn5, whereas the zero-resistance transition temperature is relatively unchanged for 0.5<x<1.
