本文报道了用In-NQR方法研究CeIrIn在压力（P）下的超导特性。在CeCoIn 5和CeRhIn 5中，超导电性（SC）的发生与源于反铁磁量子临界点（AFM-QCP）的反铁磁自旋涨落（AFM-SFs）有关。两种化合物均实现了高Tc SC（Tcmax > 2K）。然而，在CeIrIn 5中，这是除了AFM-QCP，SC发生，即使没有AFM-SF和相当小的值的Tcmax（~ 1 K），观察到约P = 3 GPa。CeIrIn 5中的SC机制可能与CeCoIn 5和CeRhIn 5中的SC机制不同。
We report the superconducting characters in CeIrIns studied by In-NQR measurements under pressure (P). In CeCoIn5 and CeRhIn5, the occurrence of superconductivity (SC) is related with the antiferrmagnetic spin fluctuations (AFM-SFs) originating from the antiferromagntic quantum-critical point (AFM-QCP). The high-Tc SC (Tcmax > 2 K) is realized in both compounds. However, in CeIrIn5 which is apart from the AFM-QCP, SC occurs even without AFM-SFs and the quite small value of Tcmax (~ 1 K) is observed around P = 3 GPa. The mechanism of SC in CeIrIn5 may be different from that in CeCoIn5 and CeRhIn5.
