Estimation of the spin polarization for Heusler-compound thin films by means of nonlocal spin-valve measurements: Comparison of Co${}_2$FeSi and Fe${}_3$Si

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, Co${}_2$FeSi (CFS) or Fe${}_3$Si (FS). T…
