N2 - Oscillations in the transverse magnetoresistance of β-(BEDT-TTF)2I3 and β-(BEDT-TTF)2IBr2 were observed below 4.2 K in fields above 9 Tesla applied perpendicular to the a-b plane. The period of the resistance oscillation vs the inverse magnetic field proved that the cross-sectional area of the two-dimensional Fermi surface was nearly a quarter of the first Brillouin zone for both β-(BEDT-TTF)2I3 and β-(BEDT-TTF)2IBr2. Beat–like phenomenon in the magnetoresistance oscillation was also observed in both salts, and its origin is discussed. The fact that the two salts are quite similar in Shubnikov-de Haas effect suggests that the difference in the band structure in the low- and high-Tc states of β-(BEDT-TTF)2I3 is small.
