dc.description.abstractWe consider the effect of nonmagnetic impurities on the onset temperature T* for the d-wave pairing in spin-fluctuation scenario for the cuprates. We analyze intermediate coupling regime when the magnetic correlation length xi/a>1 and the dimensionless coupling u is O(1). In the clean limit, T*approximate to 0.02v(f)/a in this parameter range and weakly depends on xi and u. We found numerically that this universal pairing scale is also quite robust with respect to impurities: the scattering rate Gamma(cr) needed to bring T* down to zero is about four times larger than in weak coupling, in good quantitative agreement with experiments. We provide analytical reasoning for this result.en_US
