Conventional $s$-Wave Superconductivity in Noncentrosymmetric Ir${}_2$Ga${}_9$: ${}^{71}$Ga-NQR Evidence

A. Harada, N. Tamura, H. Mukuda +4

We report a ${}^{71}$Ga nuclear-quadrupole-resonance (NQR) study on the characteristics of superconductivity in noncentrosymmetric Ir${}_2$Ga${}_9$ at zero field (H=0). The ${}^{71}$Ga-NQR…
