Abstract

The spin susceptibility at the antiferromagnetic wave vector of the normal state of high-T_c cuprates is calculated on the basis of the mode-mode coupling theory of the spin fluctuation in 2D taking the superconducting fluctuation into account. The spin-gap behavior is obtained for s or d_xy pairing but not for extended-s or d_x²-y² pairing when the Fermi surface is technically "nested". This result together with the consideration on the effect of impurity scatterings may suggest d_xy pairing and lead to a view point to understand the superconducting mechanism from charge-transfer fluctuations.
