Abstract

The behavior of de Haas–van Alfven (dHvA) and Shubnikov–de Haas (ShdH) quantum oscillations in dual-layered quasi-two-dimensional organic metal (ET)4HgBr4(C6H4Cl2) is investigated. The oscillation spectra qualitatively agree with theoretical calculations of the bandgap structure. The angular dependence of the oscillation amplitude of magnetoresistance contains “spin zeros”; the analysis of the location of these zeros allows one to evaluate the electron–phonon interaction constant: λ ≈ 0.2.
