Electron transport property in the nanocontacting wire was investigated by measuring magnetoresistance effect. In the regime of conductance quantization, the magnetoresistance exhibits the quantized step (in the unit of e2/h) and nonquantized step (ΔG < e2/h). The magnetoresistance effect appears to be large in the case that either of the steps was observed in a magnetoresistance curve, indicating that there are different mechanisms which bring about the giant magnetoresistance.
