Özet

We derive a spin-diffusion length at 4.2 K in sputtered Au, l(sf)(Au)=35(-5)(+65) nm, spin-memory-loss at Au/Cu interfaces, delta(Au/Cu)=0.13(-0.02)(+0.08), and Au/Cu interface specific resistance, 2AR(Au/Cu)=0.35(-0.05)(+0.10) fOmega m(2). We also show that exchange biased spin valves with Au sandwiched between Co layers produce changes in specific resistance, ADeltaR, comparable to those for Cu and Ag.
