Query: Comparison of the use of NiFe and CoFe as electrodes for metallic
  lateral spin-valves   Spin injection and detection in Co60Fe40-based all-metallic lateral
spin-valves have been studied at both room and low temperatures. The obtained
spin signals amplitudes have been compared to that of identical Ni80Fe20-based
devices. The replacement of Ni80Fe20 by CoFe allows increasing the spin signal
amplitude by up to one order of magnitude, thus reaching 50 m{\Omega} at room
temperature. The spin signal dependence with the distance between the
ferromagnetic electrodes has been analyzed using both a 1D spin transport model
and finite elements method simulations. The enhancement of the spin signal
amplitude when using CoFe electrodes can be explained by a higher effective
polarization.
