Abstract
We derive a spin-diffusion length at 4.2 K in sputtered Au, lsfAu=35−5+65 nm, spin-memory-loss at Au/Cu interfaces, δAu/Cu=0.13−0.02+0.08, and Au/Cu interface specific resistance, 2ARAu/Cu=0.35−0.05+0.10 fΩ m2. We also show that exchange biased spin valves with Au sandwiched between Co layers produce changes in specific resistance, AΔR, comparable to those for Cu and Ag.
