The Fermi surface of the molecular conductor (DMe-DCNQI) 2 Cu (DMe-DCNQI= 2, 5-dimethyl-N, N’-dicyanoquinonediimine) has been investigated by the de Haas–van Alphen method. Seven different oscillations with heavy cyclotron masses are observed at frequencies lower than 3000 T. These effects arise from the three-dimensional (3D) Fermi surface which is dominated mainly by the Cu 3d orbital character. Many oscillations with frequency higher than 3000 T are detected for the magnetic field in the ab plane—an effect which demonstrates the coexistence of the 1D and 3D Fermi surfaces.
