Quantum oscillations in coupled orbits networks of (BEDT-TTF) salts with tris(oxalato)metallate anions

Band structure calculations relevant to bis-ethylenedithio-tetrathiafulvalene-based charge transfer salts con- taining tris(oxalato)metallate anions, with generic formula (BEDT-TTF)$_4$A[M(C$_2$O$_4$)$_3$]·Solv, where A is a mo- novalent anion, M is a trivalent cation and Solv is a solvent, suggest that their Fermi surface is liable to achieve networks of compensated orbits coupled by magnetic breakdown. Even though this picture accounts for quantum oscillations spectra of a number of these compounds, puzzling results can be noticed in several cases, pointing to the possibility of Fermi surface reconstruction at low temperature.
