Abstract
A simple quasiclassical model is presented to explain the large, highly anisotropic magnetoresistance and striking magnetoresistance dips at magic angles in the Bechgaard salts, (TMTSFX. In the presence of a magnetic field the electrons are swept along the open orbit sheets of the Fermi surface into ‘‘hot spots’’ where the scattering rate is high. At magic angles the commensurate motion allows some fraction of the electrons to avoid the hot spots. A striplike hot region seems appropriate for (TMTSF and suggests a strong role for electron interactions.
