Abstract

We have studied the chemical-pressure effect on the Neel temperature (TN) due to the substitution of Ir for Rh in the layered heavy fermion compound CeRhIn5 by nuclear quadrupolar resonance (NQR) technique. We find that TN increases slightly upon replacing Ir for Rh up to the Ir content of 0.45. This feature resembles that in hydrostatically pressurized CeRhIn5 below 1.0 GPa where TN shows a similar dependence against pressure.
