The Hall conductivity in the magnetic-field-induced spin-density-wave (FISDW) state of the quasi-onedimensional 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 exp...
