| Outline of Final Research Achievements |
Waveguides for spin waves were developed as the analogy of optical waveguides. Spin waves are collective precession of magnetic moments (spins) in magnetic media. Such spin waves have similar characteristics with optical waves. However several essential techniques to use these spin waves in devices have not been developed. To overcome this issue, fundamental properties of spin wave waveguide were studied. The material of the spin wave waveguide was yttrium iron garnet, processed into waveguide shapes. The magnonic band gap was excited with metallic periodic structure. The spin wave waveguide medium was prepared on polycrystalline substrates with buffer layers. The magnetic properties of the prepared films with various conditions were studied.
