摘要：
在量子反磁 regime 中，边缘通道的存在导致长距离无耗散电荷传输。当石墨烯与磁性材料接口时，交换相互作用消除了 Landau 水平的自旋简并性。这导致了具有相反自旋极化方向的反向流动边缘通道的存在。我们理论表明，这些边缘通道之间的自旋翻转散射能够实现大于 100% 自旋极化的无耗散自旋传输。它还允许在没有施加电荷电流的情况下，实现宏观长距离的自旋传输。
英文摘要：
The presence of edge channels in the quantum Hall regime leads to dissipationless charge transport over long distances. When graphene is interfaced with a magnetic material, the exchange interaction lifts the Landau levels spin degeneracy. This causes the presence of counterflowing edge channels with opposite spin polarization. We show theoretically that the spin-flip scattering between these edge channels enables a dissipationless spin transport with larger than 100% spin polarization of the charge current. It also allows the transport of spin over macroscopically long distances, even in the absence of an applied charge current.
