| Outline of Final Research Achievements |
In this study, we fabricated ferromagnetic Fe3Si / semiconducting FeSi2 artificial lattices, and electrical spin injection from the Fe3Si layer to the FeSi2 layer was studied based on local 2-terminal and non-local 4-terminal type spin valve effects. For experiments with the local 2-terminal element, the generation of spin-polarized current from the Fe3Si layer to the FeSi2 layer was confirmed. In addition, it was found that the spin diffusion length (transport length) in FeSi2 is at least 100 nm. For experiments with the nonlocal 4-terminal element, it was demonstrated that pure spin current can be generated from the Fe3Si layer into the FeSi2 layer.
