摘要
A link between the spin fluctuation and ``fermiology'' is explored for the single-band Hubbard model within the fluctuation exchange 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. For ${\mathrm{La}}_{2\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{CuO}}_{4}$ 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 can still be understood within this scope if the second-nearest-neighbor hopping decreases with hole doping.
