摘要：
The magnetic-field dependence of linear and nonlinear electric conductivity in spin-density waves (SDW's) in organic conductors is studied within mean-field theory. Particular attention is paid to the low-temperature behavior and to systems with large imperfect nesting. We find that both the quasiparticle energy and the threshold electric field depend strongly on the magnetic field. The present results describe quite well the large magnetoresistance and the magnetic-field-dependent threshold electric field recently observed in SDW's of (TMTSF)2NO3.
