摘要：

On the basis of the Emery model in the limit U(d) --> infinity, the electrical resistivity is calculated by means of the memory function method. The inelastic scattering of oxygen holes on transverse and longitudinal antiferromagnetic spin fluctuations of copper spins is considered. Assuming a Fermi-liquid model for the dynamic spin susceptibility, the two-dimensional spin-fluctuation resistivity reveals a crossover from a quadratic to a linear temperature dependence. This may explain the normal-state basal-plane resistivity of high-T(c) superconductors, in particular the observed non-linear temperature dependences.
