Query: Spin Susceptibility and Specific Heat in the d-p Model   We analyze the two-dimensional {\it d-p} model, considering both
antiferromagnetic spin fluctuation and $d_{x^2-y^2}$-wave superconducting
fluctuation. We adopt the fluctuation-exchange approximation in order to derive
both normal and anomalous vertices composed only of the renormalized {\it
d}-electron Green function and the on-site repulsive interaction among the {\it
d}-electrons. Using these vertices, we derive a $t$-matrix as a superconducting
fluctuation propagator. Then, we obtain self-consistent solutions in which the
system is close to antiferromagnetic instability. In our solutions, the
superconducting fluctuation couples strongly with the quasiparticle state and
this causes the anomalous behavior in the temperature dependences of spin
susceptibility and specific heat.
