Fermi surface and effect of high magnetic fields on the metal–semimetal Peierls-like transition of (TSeT)₂Cl
Resistance measurements in pulsed magnetic fields up to 55 T as well as a first-principles DFT calculation of the Fermi surface for the organic metal (TSeT)₂Cl have been performed to investigate its metal–semimetal phase transition. The results obtained are in line with the imperfect nesting that ca...
