|Outline of Final Research Achievements
A new experimental system of microscopic nano-spectroscopy was prototyped, combining magnetic circular dichroism spectroscopy and scanning tunneling microscope with atomic resolution. From the consideration of local optical field enhancement in the vicinity of a metal tip, it was found that optical field enhancement is very weak when circular polarization modulation is used, as compared with ordinary light STM. As a sample candidate for dichroic spectroscopy, structural evaluation of amyloid beta at the atomic level was performed. Fibrils and aggregation nuclei of amyloid beta were observed by scanning probe microscopes.
