摘要：

Calculations of magnetoresistance in model quasi-two-dimensional systems are carried out as a function of field angle and intensity using Boltzmann transport theory in order to understand the angular-dependent oscillation recently found in organic conductors. The calculated resistance curves show the oscillations reminiscent of those experimentally found. The oscillations are considered to be a semiclassical effect rather than a quantum effect, in that the oscillations come from the difference of the high field asymptotic behavior of semiclassical magnetoresistance which arises from Fermi surface topology. The present model gives a natural explanation for the fact that the angular-dependent oscillation can be observed even when no Shubnikov-de Haas effect is seen.
