Odd-frequency pairing in (TMTSF)2ClO4

Abstract

The low field phase of the organic superconductor (TMTSF)2ClO4 is studied by muon spin rotation. The zero temperature limit of the magnetic penetration depth within the TMTSF layers is obtained to be lambda_{ab}(0) = 0.86(2) um. Temperature dependence of the muon spin relaxation shows no indication of gap nodes on the Fermi surface nor of any spontaneous fields due to time-reversal-symmetry breaking. The weight of evidence suggests that the symmetry of this low field phase is odd-frequency p-wave singlet; a novel example of odd-frequency pairing in a bulk superconductor.
