Outline of Final Research Achievements |
Generation methods of spin current - a flow of magnetism - originating from magnetic and mechanical motion in ferromagnetic nanostructures have been investigated. Theoretical study shows that high magnetic anisotropy materials can significantly stabilize a voltage signal arising from magnetic domain wall motion in nano-magnets making its magnitude 100 times larger than those observed previously. Some device applications based on this effect are also proposed. In addition, fluid motion of a liquid metal is shown to generate a spin current, which has been confirmed experimentally in collaboration work with an experimental group.
