    Abstract

    The oscillatory magnetoresistance spectrum of the organic metal (BEDO) 5Ni(CN) 4. 3C 2H 4(OH) 2 has been studied up to 50 T, in the temperature range from 1.5 K to 4.2 K. In high magnetic field, its Fermi surface corresponds to a linear chain of quasi-two-dimensional orbits coupled by magnetic breakdown (MB). The scattering rate consistently deduced from the data relevant to the basic α and the MB-induced β orbits is very large which points to a significant reduction of the chemical potential oscillation. Despite of this feature, the oscillations spectrum exhibits many frequency combinations. Their effective masses and (or) Dingle temperature are not in agreement with either the predictions of the quantum interference model or the semiclassical model of Falicov and Stachowiak. © EDP Sciences/Società Italiana di Fisica/Springer-Verlag 2007.
