| Research Abstract |
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.
