Outline of Final Research Achievements |
In this study, we employed a Weyl magnetic material to realize a highly-sensitive and highly-precise Hall sensor. We selected a few materials from the predicted candidates of Weyl magnets, which have attracted attention from the viewpoint of basic science yet, and investigated deposition processes for their epitaxial growth. We expect early demonstration of this concept by a high-quality thin-film growth technique and proper elemental substitution to design its electronic and magnetic structure, leading to development of sensing technologies for the smart society.
