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.

载流子自旋极化态的积累和自旋电子电池

考虑了基于材料的自旋阀，其中通过电荷载流子的空间分离抑制自旋翻转，同时保持阀体积中的电中性。讨论了将这些阀用作电池的可能性。结果表明，如果控制阀门两端的电位差，则可能会出现“魔鬼阶梯”等不可公度效应，这与电池充电和放电时发生的库仑相互作用和电子重新分布有关。预测了随着阀中费米能级的变化，传导电子的自发自旋极化的出现和消失的影响。这种自旋阀也可用于实现自旋电子存储单元、超级电容器和类似设备。
