Spin-scattering asymmetry at half-metallic ferromagnet/ferromagnet interface
Y. Fujita, Y. Miura, T. Sasaki +3
We study spin-scattering asymmetry at the interface of two ferromagnets (FMs) based on a half-metallic CoFeMnSi (CFMS)/CoFe interface. First-principles ballis…
Room-temperature spin transport in n-Ge probed by four-terminal nonlocal measurements
Michihiro Yamada, Makoto Tsukahara, Yuichi Fujita +4
We demonsrtate electrical spin injection and detection in -type Ge (-Ge) at room temperature using four-terminal nonlocal spin-valve and Hanle-effect measurements in lateral…
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…
Room-temperature detection of spin accumulation in silicon across Schottky tunnel barriers using a MOSFET structure
K. Hamaya, Y. Ando, K. Masaki +5
Using a metal-oxide-semiconductor field effect transistor (MOSFET) structure with a high-quality CoFe/n^+Si contact, we systematically study spin injection and spin accumulation in…
