The mapping of the quasi-two-dimensional Fermi surface sections of organicconductors

We have developed a model for parameterizing the shape of the quasi-two-dim ensional (Q2D) Fermi surface (FS) sections found in many organic molecular metals. Using this model, we show that it is possible to extract more detai l about the Q2D pocket shape from angle-dependent magnetoresistance oscilla tions than in the traditional approximation which assumes an elliptical FS shape. We also consider the implications for cyclotron resonance experiment s.
