中文摘要	We report B-11 NMR measurements in noncentrosymmetric superconductors Mg9.3Ir19B16.7 (T-c=5.8 K) and Mg10.5Ir19B17.1 (T-c=4.8 K). The spin-lattice relaxation rate and the Knight shift indicate that the Cooper pairs are predominantly in the spin-singlet state with an isotropic gap. However, Mg10.5Ir19B17.1 is found to have more defects and the spin susceptibility remains finite even in the zero-temperature limit. We interpret this result as that the defects enhance the spin-orbit coupling and bring about more spin-triplet component.
