Abstract

The low-field phase of the organic superconductor (TMTSF) 2 ClO 4 is studied by muon-spin rotation. The zero temperature limit of the magnetic penetration depth within the TMTSF layers is obtained to be λ ab (0)=0.86(2) μm . 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.
