Low-field superconducting phase of (TMTSF)2ClO4.

Pratt, F.L. and Lancaster, T. and Blundell, S.J. and Baines, C. (2013) 'Low-field superconducting phase of (TMTSF)2ClO4.', Physical review letters., 110 (10). p. 107005.


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.
