Outline of Final Research Achievements

This research aimed to clarify the scientific prinsiple of nano spin-ionics and to demonstrate an application to functional electronics. Electric effects in a solid electrolyte including a magnetic ion were investigated. The role of ions for the magnetism in carbon-based materials was also investigated, and it was proved that addition of ions paves the way for inducing magnetization in the materials.
