A study of superconductivity in the noncentrosymmetric phase of NbxRe1-x

DOI

Noncentrosymmetric superconductors have been identified as good candidates for unconventional superconductivity. In particular there is the possibility of Cooper pairs with mixed pairing symmetries. NbxRe1-x forms a noncentrosymmetric structure for 0.13<x<0.38 with a Tc of 8.8 K for x = 0.18. We wish to carry out zero and longitudinal field muon spin relaxation measurements and transverse field muon spin rotation measurements on up to three powder samples with different values of x down to 0.3 K. This is primarily to look for broken time reversal symmetry and to measure the magnetic penetration depth as a function of temperature. This will be used to deduce information about the gap symmetry. Since this structure is present over a wide range of x, it will be possible to examine the effects on the pairing symmetry of adding or removing heavy atoms and altering the spin-orbit coupling.
