Outline of Final Research Achievements

Spin wave is the information transport technology of spin information with low energy consumption. Furthermore multiple spin information are expected to be transported by using multiple spin waves with different wave length. To establish the technology of multiple spin wave transport, deconvolution techniques of each spin wave is desired. The final goal of this study is to establish the deconvolution techniques by using the Snell's law of spin wave at the ferromagnetic material / ferromagnetic material interface. In this study, we investigated growth of ferromagnetic Heusler alloy and Yttrium Iron Garnet (YIG) which have a low Gilbert damping constant. We also investigate dominant factor of the Gilbert damping constant in YIG which enables long distance transport of the spin waves.
