Spin injection into multilayer graphene from highly spin-polarized Co2FeSi Heusler alloy
Takehiro Yamaguchi, Rai Moriya, Yoichiro Oki +4
We demonstrate electrical spin injection into multilayer graphene (MLG) in a lateral spin valve device from a highly spin-polarized Co2FeSi (CFS) Huesler electrode. Exfoliated MLG…
Direct Evidence for Suppression of the Kondo Effect due to Pure Spin Current
K. Hamaya, T. Kurokawa, S. Oki +3
We study the effect of a pure spin current on the Kondo singlet in a diluted magnetic alloy using non-local lateral spin valve structures with highly spin polarized Co2FeSi electro…
Effect of Co-Fe substitutions on the room-temperature spin polarization in Co_3-xFe_xSi Heusler-compound films
K. Tanikawa, S. Oki, S. Yamada +3
Using low-temperature molecular beam epitaxy, we study substitutions of Fe atoms for Co ones in Co_3-xFe_xSi Heusler-compound films grown on Si and Ge. Even for the low-temperature…
Estimation of the spin polarization for Heusler-compound thin films by means of nonlocal spin-valve measurements: Comparison of CoFeSi and FeSi
K. Hamaya, N. Hashimoto, S. Oki +3
We study room-temperature generation and detection of pure spin currents using lateral spin-valve devices with Heusler-compound electrodes, CoFeSi (CFS) or FeSi (FS). T…
