Abstract
A quasi-two-dimensional (ET)8Hg4Br12(C6H5Cl)2 organic metal undergoes the metal–dielectric transition at T ~ 90 K upon cooling. An external pressure of P ~ 6 kbar completely recovers the metallic state and makes it possible to observe the Shubnikov–de Hass oscillations with a frequency of F ≈ 215 T and a cyclotron mass of m* ≈ 0.95m0. The behavior of the oscillations is consistent with the Fermi surface representation in the form of electron and hole orbits covering the same areas of the first Brillouin zone.
