| Outline of Final Research Achievements |
The present study is aimed to develop a new magnetic imaging technique using electron vortex beams, the new propagation mode of electron beams, and to reveal the interaction between electron vortex beams and magnetic materials and magnetic fields. This study is focused mainly on the generation of electron beams carrying orbital angular momenta and their propagation properties, a new phase imaging technique using electron vortex beams. The following studies have been carried out. 1) Generation of electron vortex beams at a high beam energy of 1000keV using a high-voltage reaction science microscope. 2) Development of an electron diffractive imaging technique using fork-shaped gratings. 3) Generation of nondiffracting electron beams carrying orbital angular momentum. 4) Measuring orbital angular momentum using Danmann vortex gratings. 5) Experimental verification of the creation and annihilation of Skyrmions using electron vortex beams
