When a quantum wire is weakly confined, a conductance plateau appears at e;2/h with decreasing carrier density in zero magnetic field accompanied by a gradual suppression of the 2e;2/h plateau. Applying an in-plane magnetic field B parallel does not alter the value of this quantization; however, the e;2/h plateau weakens with increasing B parallel up to 9 T, and then strengthens on further increasing B parallel, which also restores the 2e;2/h plateau. Our results are consistent with spin-incoherent transport in a one-dimensional wire.
