The electrical injection of the spin-polarized current into silicon in the Fe3Si/n-Si epitaxial structure is demonstrated. The spin accumulation effect is examined by measuring the local and nonlocal voltage in a special four-terminal device. The observed effect of the electric bias on the spin signal is discussed and compared with the results obtained for ferromagnet/semiconductor structures.
