| Research Abstract |
The regular nanospace can be provided by the zeolite crystals, where cages are arrayed by the sharing of windows. By the loading of guest alkali metals into the nanospace at various densities, s-electrons in cages have the localized properties by the quantum confinement and the repulsive interactions as well as the itinerancy through the windows of cages. Furthermore, the electron-lattice interaction due to the displacement of cations in cages plays an important role in the state of s-electrons. We investigated the different properties of these exotic nanomaterials, and have found new phenomena which are not expected from the ordinal properties of constituent elements, such as ferromagnetism, insulator-to-metal transition, etc.
