Abstract

Shubnikov-de Haas (SdH) measurements in the quasi-two-dimensional (2D) organic conductor (BEDT-TTF)2TlHg(SCN)4 have been carried out to investigate the ground state. The closed orbit of the 2D Fermi surface and the magnetic breakdown orbit are observed above 10 T. Below 3 T, three small closed orbits are found, which are made by the nearly perfect nesting of the one-dimensional (1D) Fermi surface. The results indicate that the ground state is a spin density wave state at low magnetic fields and that the nesting is removed by high magnetic fields.
