Pressure- and temperature-dependent heat capacity and electrical resistivity experiments on Sn- and La-doped CeRhIn(5) are reported for two samples with specific concentrations, Ce(0.90)La(0.10)RhIn(5) and CeRhIn(4.84)Sn(0.16), which present the same T(N)=2.8 K. The obtained P-T phase diagrams for doped CeRhIn(5) compared to that for the pure compound show that Sn doping shifts the diagram to lower pressures while La doping does exactly the opposite, indicating that the important energy scale to define the pressure range for superconductivity in CeRhIn(5) is the strength of the on-site Kondo coupling.1011
