摘要:

自旋阀的基础上的材料,其中自旋翻转被抑制的空间分离的载流子,同时保持电中性的阀体积,被认为是。使用这些阀门作为电池的可能性进行了讨论。它示出,如果跨阀的电势差的控制,不可吸收性的影响,如“魔鬼的楼梯”,这是与库仑相互作用和重新分配的电子发生,而电池充电和放电可能是预期的。预测了电子自发自旋极化的出现和消失随费米能级变化的影响。这样的自旋阀也可以用于实现自旋电子存储器单元、超级电容器和类似器件。

英文摘要:

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.
