Organic conductors in high magnetic fields: Model systems for quantum oscillation physics

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. (C) 2012 Academie des sciences. Published by Elsevier Masson SAS. All rights reserved.
