Abstract
We present the first measurements of the specific resistance change, AΔR, with increasing Co layer thickness, tCo of current-perpendicular (CPP) exchange-biased spin-valves (EBSVs) of Co and Cu. AΔR grows about as predicted for a long spin-diffusion length in Co until about tCo = 20 nm, after which it grows more slowly than predicted. Possible reasons for this deviation from prediction are considered, including a short spin-diffusion length in Co.
