摘要：
We report zero-field-muSR studies of cerium-based heavy-fermion materials CeRh1-xIrxIn5. In the superconducting x = 0.75 and 1.0 compositions, muon spin relaxation functions were found to be temperature independent across T-c; no evidence for the presence of electronic magnetic moments was observed. The x = 0.5 material is antiferromagnetic below T-N = 3.75 K and superconducting below T-c = 0.8 K. muSR spectra show the gradual onset of damped coherent oscillations characteristic of magnetic order below T-N. At 1.65 K the total oscillating amplitude accounts for at least 85% of the sample volume. No change in precession frequency or amplitude is detected on cooling below T-c, indicating the microscopic coexistence of magnetism and superconductivity in this material.
