$s$-wave superconductivity in the noncentrosymmetric W${}_3$Al${}_2$C superconductor: An NMR study

D. Tay, T. Shang, Y. P. Qi +4

We report on a microscopic study of the noncentrosymmetric superconductor W${}_3$Al${}_2$C (with $T_c$ = 7.6 K), mostly by means of ${}^{27}$Al- and ${}^{13}$C nuclear magnetic resonance (…
