Abstract
We study theoretically the effects of imperfect nesting in spin-density waves (SDW’s) in quasi-one-dimensional systems. We analyze the phase diagram, the specific heat, and the threshold electric field in the presence of imperfect nesting. The latter result appears to describe the temperature dependence of the threshold electric field observed in SDW’s of quenched di-tetramethyl-tetraselena-fulvalene chlorate [(TMTSF] observed by Shimizu et al.
