| Abstract: | By a transfer matrix method, we investigated the Hall conductance of a long quantum wire under real magnetic barriers. It was found that the step Hall conductivities can be observed, and with the increase of the Fermi energy, the conductor is quenched and then the negative Hall conductivity of strong oscillation emerges. |

| Keywords: | quantum wire systems the negative Hall conductivity the Hall conductivity quenching |
