${}^{181}$Ta Nuclear quadrupole resonance study of non-centrosymmetric superconductor PbTaSe${}_2$

K. Yokoi, M. Yashima, H. Murakawa +5

We report on a pure ${}^{181}$Ta-nuclear quadrupole resonance (NQR) measurement of PbTaSe${}_2$ at zero magnetic field, which has the advantage of directly probing the intrinsic superc…
