Outline of Final Research Achievements

We have developed the imaging method of electromagnetic fields based on the data analysis of small-angle electron scattering experiments, which have significant advantages in quantitative detection of electromagnetic field distributions. Using small-angle electron scattering experiments, we clarified very fine magnetic structures of chiral magnetic orders uniquely formed in chiral helimagnets, which are one of promising materials for the next-generation spin electronics. The present methods will be utilized as fundamental method to perform quantitative analysis of electromagnetic field distributions or fine magnetic/dielectric structures in artificial magnetic lattice, spin electronics, or dielectric materials.
