摘要：
Analysis of the temperature and field dependence of the de Haas-van Alphen oscillations in an organic superconductor theta-(BEDT-TTF)2I3 is presented. The cyclotron masses are estimated to be 2.0m(e) and 3.6m(e) for slow and fast oscillations, respectively. The indication of magnetic breakdown effect is discussed in terms of the geometry of the Fermi surface. The result is compared with those of the infrared reflectance spectra and the empirical tight-binding band calculations.
