Abstract: This paper reports on measurements of the de Haas-van Alfven effect in the quasi-two-dimensional organic conductor (BEDT-TTF)(8)Hg4Cl12 (C6H5Cl)(2) performed within the temperature range 0.33-1.44 K in magnetic fields of B less than or equal to 50 T. An analysis of quantum oscillations together with cyclotron resonance data obtained in the 40-120-GHz frequency range revealed that the complex quantum-oscillation spectrum is formed by the fundamental frequencies alpha similar to 256 T and beta similar to 670-610 T, as well as by combination and multiple frequencies. It is shown that the character of the temperature-induced oscillation-spectrum rearrangement can be interpreted within a model taking into account the existence of a magnetic phase transition at T-c similar to 0.9 K and the closeness of the fundamental frequency alpha with effective mass m* = 1.48m(0) to the spin damping condition.
