Résumé
Abstract

Bien que les conducteurs organiques présentent des structures cristallines complexes et de basse symétrie, les calculs prédisent une structure électronique multibande quasi-bi dimensionnelle conduisant généralement à une surface de Fermi très simple. Bien que quelques résultats expérimentaux déroutants soient observés, les données de nombreux composés sont en accord avec les calculs, ce qui fait de ces derniers des systèmes modèles pour la physique des oscillations quantiques dans les réseaux dʼorbites couplées par la rupture magnétique. Lʼétat de lʼart de cette problématique est passée en revue.

Even although organic conductors have complicated crystalline structures with low symmetry and large unit cells, band structure calculations predict a multiband quasi-two-dimensional electronic structure yielding a very simple Fermi surface in most cases. Although few puzzling experimental results have been observed, data for numerous compounds are in agreement with calculations, which make them suitable systems for studying magnetic quantum oscillations in networks of orbits connected by magnetic breakdown. The state of the art of these problematics is reviewed.
