Observation of giant magnetoresistance oscillations in the high-Tc phase of the two-dimensional organic conductor β-(BEDT-TTF)2I3
Résumé
Giant Shubnikov de Haas oscillations have been observed in the high-Tc phase (βH) of an organic conductor-(BEDT-TTF)2I3. The frequency of the oscillations (H0=3730 T) Corresponds to about one carrier per unit cell. The extraordinary large amplitude of the magnetoresistance oscillations has been attributed to the two-dimensional nature of the cylindrical Fermi surface exhibiting only a small warping along the direction of lowest conductivity.
