抄録

By including the higher order terms in the RPA in addition to the leading order terms of the 1/N-expansion, the spin susceptibility χ^s (q) and the charge susceptibility χ^c (q) are investigated in the d-p model with the infinite on-site repulsion U_d at the Cu-site and with the repulsion U_pd between holes on the nearest-neighbor O- and Cu-sites.In this way the spin and charge fluctuations are taken into account on a common basis.In the low doping region, the antiferromagnetic order (AF) or the spin density wave (SDW) arises due to the nesting on the large Fermi surface in the in-gap state and the quasi-particle interaction at the low temperature.The enhancement of χ^c due to U_pd is found only in the over doping region, whereas in the leading order in the 1/N-expansion it is found in the whole doping region.
