Temperature Evolution of the Quantum Hall Effect in Quasi-One-Dimensional Organic Conductors

Abstract

The Hall conductivity in the magnetic-field-induced spin-density-wave (FISDW) state of the quasi-one-dimensional organic conductors (TMTSF)${}_2$X at a finite temperature is calculated. The temperature dependence of the Hall conductivity is found to be the same as the temperature dependence of the Fröhlich current of a regular charge/spin-density wave. Predicted dependence ${\sigma }_{xy}(T)$ can be verified experimentally in the (TMTSF)${}_2$X compounds if all components of the resistivity tensor are measured and the conductivity tensor is reconstructed.
