Recently, control of pure spin current have attracted a great deal of attention as a method of dissipation-free information propagation. An electrical method, general spin-generation method, made significant advances and is utilized for the magnetic head. However, although a dynamical method without the application of charge current directly has been gaining importance, its low efficiency is an issue. In this study, we explored possible materials to realize highly efficient spin injection and realized about 20 times higher efficient than previous study using single-crystalline Fe3Si as a spin injector. Furthermore, we clarified a mechanism for the highly efficient spin injection. |
