自旋方向表示电子自旋的方向。自旋量子数等于1/2，表示电子顺着磁场方向取向，用↑表示，说成逆时针自旋；自旋量子数等于-1/2表示逆着磁场方向取向，用↓表示，说成顺时针自旋。

-
我们把碳纳米管放在磁性电极之间。然后我们发现被碳纳米管捕捉的单电子自旋方向可以被电势直接控制。
We have placed the nanotubes between magnetic electrodes and we have shown that the direction of a single electron spin caught on the nanotube can be controlled directly by an electric potential.
-
特别是随着时间的演化，系统的平均自旋方向的分布和摆动也与初态所处的空间结构有着密切的联系。
In particular, with time evolution, distribution and swing of the mean spin direction is closely related to the structure of the space where the initial coherent state centred in.
-
巨磁电阻的产生是因为每一个电子带有一个特定方向的自旋。
GMR arises because each electron carries a spin that points in a specific direction.
-
So you can see, if it's spinning on its own axis in this direction we'd call it spin up, where as this way it would be what we call spin down.
你们可以看到，如果它绕自己的轴朝这个方向转,我们就说它是自旋朝上，这个方向我们叫它自旋朝下。
