Large enhancement in the generation efficiency of pure spin currents in Ge using Heusler-compound Co_2FeSi electrodes
K. Kasahara, Y. Fujita, S. Yamada +3
We show nonlocal spin transport in n-Ge based lateral spin-valve devices with highly ordered Co_2FeSi/n^+-Ge Schottky tunnel contacts. Clear spin-valve signals and Hanle-effect cur…
Giant enhancement of spin pumping efficiency using Fe3Si ferromagnet
Y. Ando, K. Ichiba, S. Yamada +4
Spincurrentronics, which involves the generation, propagation and control of spin currents, has attracted a great deal of attention because of the possibility of realizing dissipat…
Dynamical Spin Injection into p-type Germanium at Room Temperature
Mariko Koike, Eiji Shikoh, Yuichiro Ando +4
We demonstrate dynamical spin injection into p-type germanium (Ge) at room temperature (RT) using spin pumping. The generated pure spin current is converted to a charge current by…
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…
