The superconducting order parameter in the organic layered superconductor k-(BEDT-TTF)2Cu[N(CN)2]Br
Highly sensitive ac susceptibility measurements were performed in order to resolve the controversy regarding the symmetry of the superconducting order parameter in -BEDT-TTF materials. The experimentally obtained superfluid density behaviour qualitatively contradicts swave symmetry theoretical predictions, but disagrees also quantitatively with the d-wave expected behaviour in the weak coupling limit. The mixture of d-wave and s-wave parameters, with a rather large proportion of the latter, describes well the results ; however, it also opens new questions regarding the origin of the superconducting pairing.
