Résumé

We discuss a model of quasi-two-dimensional superconductors, in which the Fermi surface exhibit an imperfect nesting property. Nesting properties lead to important effect of antiferromagnetic fluctuations on the normal state properties, such as the resistivity, the knight shift and NMR relaxation rate, the magnetic susceptibility. These fluctuations play an important role for temperatures of the same order as the energy departure from perfect nesting(1). We discuss the relevance of this model to interpret recent experimental data in high Tc cuprate oxyde superconductors as well as organic superconductors. It seems that many properties of these various compounds might be interpreted in this way.
