| Outline of Final Research Achievements |
Research fields engineering of magnetic media with nanoscale artificial structures are becoming important technology because of their unique and interesting properties. In particular, interactions among light, spin waves, high frequency electromagnetic waves, and nanoscale structures have attracted interests because of the recent rapid development of the information communication technology. We investigated the fundamental properties of spin waves propagating in periodic spin systems, exhibiting magnonic band gap. In addition, some types of three-dimensional displays were demonstrated and improved using magnetooptical materials.
These structures, namely artificial magnetic lattices, are significantly fascinating techniques not only in the field of physics but also engineering. In this study, fundamental properties and design rules of artificial magnetic lattices controlling photons, and spin waves were experimentally and theoretically revealed.
