| Outline of Final Research Achievements |
We have developed a combination system of high-performance ultra-high vacuum scanning probe microscopy and molecular beam epitaxy equipment for the spintronics research with atomic level. The system allows us to perform thin-film preparation and atomic resolution measurement without breaking vacuum, which is expected to control an easy magnetization axis of high-performance spintronics material with high reproducibility. Using this apparatus, the appearance of the initial growth of Fe on the SrTiO 3 (100)-(R 13 × R 13) uppermost surface was observed with high resolution using a scanning tunneling microscope. We found that the structure of the initial growth was different depending on the temperature of the substrate, and it was confirmed by scanning tunneling spectroscopy.
