A recursive Green’s function technique is developed to calculate the spin-dependent conductance in mesoscopic structures. Using this technique, we study the spin-dependent electronic transport of quantum point contacts in the presence of the Rashba spin–orbit interaction. We observed that some oscillations in the “quantized” conductance are induced by the spin–orbit interaction, and suggest that the oscillations may stem from the spin–orbit coupling associated multiple reflections. It is also indicated that the 0.7 structure of the conductance observed in mesoscopic experiments would not arise from the spin–orbit interaction.
