摘要：

The Shubnikov-de Haas (SdH) effect and angular-dependent magnetoresistance oscillation (ADMRO) were observed in magnetoresistance measurements at 0.5 K for an organic conductor kappa-(BETS)(2)GaCl4. From a frequency of a SdH oscillation, a Fermi surface cross-section perpendicular to the crystallographic b-axis is estimated to be 4.20 x 10(15)cm(-2), which corresponds to 105% of the first Brillouin zone. From the results of ADMRO, a Fermi wave number along the crystallographic c-axis is evaluated to be 0.35 Angstrom(-1). Both results are consistent with a band structure calculated on the basis of the extended Huckel method.
