关于电子量子自旋Talbot效应的设想

Proposal for Electron Quantum Spin Talbot Effect

W. X. Tang, D. M. Paganin

摘要:

我们提出了一个自旋极化泰伯效应的电子束散射的磁性纳米结构的光栅。现有的周期性磁性纳米结构可以与电子束照射结合使用,以创建Talbot长度外的横向周期性出射表面光束的自旋极化复制品。在二维电子气和原子级平坦表面上,利用自旋极化扫描探针显微镜进行了实验验证。这种效应为二维空间中电子自旋分布的调制提供了一条新的途径。

英文摘要:

We propose a spin polarized Talbot effect for an electron beam scattered from a grating of magnetic nanostructures. Existing periodic magnetic nanostructures can be used in conjunction with electron-beam illumination to create a spin polarized replica of the transversely periodic exit surface beam a Talbot length away. Experiments have been proposed to verify the effect in a two dimensional electron gas and an atomically flat surface by spin polarized scanning probe microscopy. This effect provides a new route to modulate electron spin distributions in two dimensional space.
