Query: A link between the spin fluctuation and Fermi surface in high T_C
  cuprates --- A consistent description within the single-band Hubbard model   A link between the spin fluctuation and the "fermiology" is explored for the
single-band Hubbard model within the fluctuation exchange (FLEX) approximation.
We show that the experimentally observed peak position of the spin structure in
the high T_C cuprates can be understood from the model that reproduces the
experimentally observed Fermi surface. In particular, both the variation of the
incommensurability of the peak in the spin structure and the evolution of the
Fermi surface with hole doping in La_{2-x}Sr_xCuO_4 may be understood with a
second nearest neighbor hopping decreasing with hole doping.
