Abstract
The sign reversal phenomenon of the quantized Hall conductance observe d in (TMTSF)2X is explained theoretically in terms of the mean field s olution for the field-induced spin density wave (FISDW) characterized by many-order parameters (MOP). The many competing OPs can make the si gn of the Hall constant change particularly near the subphase boundary . It is shown that the jump of the Hall constant is accompanied by the energy gap closing of the FISDW.
