| Outline of Final Research Achievements |
Development of materials was carried out in order to control spin wave by using periodic nano-sized electrodes. First, voltage was applied to the fabricated samples, however, the voltage effect was not obtained. Thinning the sample was tried because it was effective to obtain a voltage effect. As a result, thinning the sample without degrading the property of the sample was successful. In addition, a multilayered structure of ferromagnetic insulator / ferromagnetic metal / nonmagnetic metal was suggested as a new system for voltage application, and the prototype of the structure was fabricated. It was found that the fabricated structure had a perpendicular magnetic anisotropy. In the future, micro-fabrication process will be optimized and the experiment for voltage application will be carried out.
