项目摘要
We have succeeded in a development of Spin-polarized and Pulsed TEM (SP-TEM) for the first time in the world. The SP-TEM has realized high performances of 90-% spin-polarization, 10-7-A/cm2sr brightness, 1.6-nm spatial resolution and less 240-meV energy spread with a beam energy of 30 keV simultaneously. It can provide a TEM image and diffraction pattern of iron thin film. Furthermore we have observed a pico-second pulsed electron beam in the SP-TEM. These results indicate that spatial-, temporal- and spin-resolved measurement is realized in this research program. It is amazing apparatus that the narrow line-width of zero-loss peak, the long spatial coherence length and the high spin-polarization are realized simultaneously. The abilities are useful to open a frontier of analytical method and research new physics and new material sciences.
我们在世界上首次成功开发了自旋极化脉冲 TEM (SP-TEM)。 SP-TEM 实现了 90% 自旋偏振、10-7-A/cm2sr 亮度、1.6 nm 空间分辨率和 30 keV 光束能量同时小于 240 meV 能量扩散的高性能。它可以提供铁薄膜的TEM图像和衍射图。此外,我们还在 SP-TEM 中观察到了皮秒脉冲电子束。这些结果表明该研究项目实现了空间、时间和自旋分辨测量。同时实现了零损耗峰的窄线宽、长空间相干长度和高自旋偏振,这是令人惊奇的装置。这些能力对于开辟分析方法的前沿以及研究新物理学和新材料科学很有用。
