摘要：

We find a striking peak structure in the magnetoresistance of the quasi-two-dimensional conductors beta-(BEDT-TTF)(2)I-3 and alpha-(BEDT-TTF)(2)NH4Hg(SCN)(4) for magnetic fields nearly parallel to the conducting plane. The peak structure can be ascribed to a Fermi-surface topological effect due to the small closed orbits on the side of the warped cylindrical Fermi surface. This effect provides a clue about how to evaluate the interlayer transfer integral.
