Using the d - p model, we demonstrate that the pseudogap, which is induced by the superconducting fluctuation, plays key roles in the determination of the phase diagram observed in high- T c superconducting materials. We take the pairing interaction mediated by the spin fluctuation and calculate the superconducting transition temperature T c , the NMR relaxation rate 1/ T 1 and the single-particle spectrum by treating both the superconducting fluctuation and spin fluctuation in a consistent…
