Query: Evidence for the Presence of Spin Accumulation in Localized States at
  Ferromagnet-Silicon Interfaces   We experimentally show evidence for the presence of spin accumulation in
localized states at ferromagnet-silicon interfaces, detected by electrical
Hanle effect measurements in CoFe/$n^{+}$-Si/$n$-Si lateral devices. By
controlling the measurement temperature, we can clearly observe marked changes
in the spin-accumulation signals at low temperatures, at which the electron
transport across the interface changes from the direct tunneling to the
two-step one via the localized states. We discuss in detail the difference in
the spin accumulation between in the Si channel and in the localized states.
