Spin-singlet superconductivity with a full gap in locally non-centrosymmetric SrPtAs

K. Matano, K. Arima, S. Maeda +4

We report ${}^{195}$Pt-NMR and ${}^{75}$As-NQR measurements for the locally non-centrosymmetric superconductor SrPtAs where the As-Pt layer breaks inversion symmetry while globally the…
