It has been recently established that the superconductivity (SC) in kappa-(BEDT-TTF)2Cu[N(CN)2]Br is extremely sensitive to the cooling procedure through 100– 70 K, where the ethylene groups attached to the BEDT-TTF molecules order with very slow relaxation times (the glass transition). In particular, the superconductivity in the annealed samples is described in terms of dx2_y2-wave, while the quenched samples have very small (by a factor of 10_2 or less) superfluid density with the different temperature dependence. In spite of this dramatic difference, the SC transition temperature of these samples is practically unchanged. We propose that this dramatic decrease in the superconductivity is due to the appearance of spin-density wave order parameter in the quenched samples.
