The production of spin-polarized electrons and the modulation of polarization direction with liquid crystal variable retarder (LCVR) are discussed.

LCVR控制入射光子的偏振度，从而实现对自旋极化电子束极化方向的调制。

The challenge, however, is extracting the spins to form a spin-polarized current and injecting them into a circuit without the polarization degrading along the way.

唯一的挑战是，如何提取自旋来形成一个自旋极化的电流，然后注入到电路中并保持极化在沿途不发生退化。

Moreover, electron-spin polarization are relevant to the structure parameters of the system, so we can control spin-polarized electronic behavior by means of adjusting ferromagnetic stripes.

而且，电子的自旋极化度与系统的结构参数密切相关，因此通过调整磁条可以调控系统中自旋极化电子的行为。

Grandis makes a non-NAND flash solid state storage technology called spin-transfer torque RAM (STT-RAM) that stores information via the direction of magnetization in a spin-polarized electron current.

If you're a frequent reader you're surely well aware of the potential of spin torque transfer memory, or STT-MRAM, and how spin-polarized magnetic currents (and the electrons they love to caress) might hold the potential to revolutionize storage as we know it.
