| Abstract | We investigate theoretically the combination effect of an in-plane magnetic field and spin-orbit interactions （SOIs） on the spin and charge transport property of a quasi-one-dimensional quantum wire embedded in the （110） crystallographic plane. We find that the oscillations of the conductance induced by the SOIs become more significant and different for the spin-up and spin-down electrons in the presence of the in-plane magnetic field. The conductance exhibits a significant anisotropic behavior and electrons exhibit out-of-plane spin polarization which can be tuned by an in-plane magnetic field. These features offer us an efficient way to control SOI-induced spin transport using in-plane magnetic fields. |
