Nonmonotonic bias dependence of local spin accumulation signals in ferromagnet/semiconductor lateral spin-valve devices
Y. Fujita, M. Yamada, M. Tsukahara +5
We find extraordinary behavior of the local two-terminal spin accumulation signals in ferromagnet (FM)/semiconductor (SC) lateral spin-valve devices. With respect to the bias volta…
Pure spin current transport in a SiGe alloy
T. Naito, M. Yamada, M. Tsukahara +3
Using four-terminal nonlocal magnetoresistance measurements in lateral spin-valve devices with SiGe, we study pure spin current transport in a degenerate Si…
Efficient spin transport along Si 100 at room temperature
M. Ishikawa, M. Tsukahara, Y. Fujita +4
We find efficient spin transport in Si at room temperature in lateral spin valves (LSVs). When the crystal orientation of the spin-transport channel in LSVs is changed from $\langl…
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…
