论文摘要
考虑了基于电荷载体的空间分离抑制自旋叶片的旋转阀，同时考虑了在阀量中保持电中心性的同时。讨论了将这些阀用作电池的可能性。结果表明，如果控制了整个阀的电势差，则可能会预期诸如“魔鬼的楼梯”之类的不可通信效应，这与库仑相互作用和电池充电和放电时发生的电子的相互作用和重新分布有关。预测了传导电子的自发自旋极化的出现和消失的影响，而阀中费米水平的变化会发生变化。这种自旋阀也可以用于实现自旋记忆单元，超级电容器和类似设备。
Spin valves based on materials in which the spin-flip is suppressed by the spatial separation of charge carriers, while maintaining electric neutrality in the valve volume, are considered. The possibility of using these valves as electric batteries is discussed. It is shown that if the potential difference across the valve is controlled, incommensurability effects such as the "devil's staircase" may be expected, which are associated with the Coulomb interaction and redistribution of electrons occurring while the battery is charged and discharged. The effects of the emergence and vanishing of spontaneous spin polarization of conduction electrons with a change in the Fermi level in the valve are predicted. Such spin valves can also be used in implementing spintronic memory cells, supercapacitors, and similar devices.
