| Outline of Final Research Achievements |
Ferromagnetic multilayers with hierarchized magnetic properties, integrated with the inter-layer exchange coupling, have been focused. The fundamental physics of the mutual conversion between the microwave field and the quanta of the three dimensional spin wave (3D magnon), where the spin wave is quantized in the in-plane and out-of-plane direction, have been investigated experimentally and numerically. The material parameters have been clarified, which enable efficient magnon emission at the operation frequency higher than 10 GHz. Fundamental device architecture and the expected performance have been clarified for signal processing devices of transmission line structures and the logic in memory devices, which utilize frequency selective excitation of 3D-magnon.
