Temperature evolution of the quantum hall effect in quasi-one-dimensional organic conductors

The Hall conductivity in the magnetic-field-induced spin-density-wave (FISDW) state of the quasi-one-dimensional organic conductors (TMTSF)2X 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 σxy(T) can be verified experimentally in the (TMTSF)2X compounds if all components of the resistivity tensor are measured and the conductivity tensor is reconstructed.
