我们提出并研究了一种自旋电池装置，它为未来的自旋电子电路提供必要的自旋动力来驱动自旋电流。我们的自旋电池有四个基本特征：(i)它有两个极点，自旋电流从一个极点流入，从另一个极点流出，这样就可以建立一个完整的自旋电路；（ii）具有驱动自旋电流的能量源；（iii）保持自旋相干性，以提供相当大的自旋电流；（iv）驱动自旋电流而不产生电荷电流。所提出的用于自旋电流的自旋细胞应该可以利用现有的技术实现。
We propose and investigate a spin-cell device which provides the necessary spin-motive force to drive a spin current for future spintronic circuits. Our spin cell has four basic characteristics: (i) it has two poles so that a spin current flows in from one pole and out from the other pole, and in this way a complete spin circuit can be established; (ii) it has a source of energy to drive the spin current; (iii) it maintains spin coherence so that a sizable spin current can be delivered; (iv) it drives a spin current without a charge current. The proposed spin cell for spin current should be realizable using technologies presently available.
