Outline of Final Research Achievements

The aim of this study is to investigate irradiation effects of Laguerre-Gauss beams on chiral inorganic solids using a synchrotron radiation X-ray scanning microscope. The observation technique of chirality domain structures has been improved to cover all the Sohncke groups. Laser beam irradiation conditions for melting and solidification have been specified for the B20-type chiral compound Fe1-xCoxSi. In addition, we have succeeded in visualizing asymmetric changes induced by optical angular-momentum transfer.
