Pd/Ag and Pd/Au interface specific resistances and interfacial spin flipping

We measured the specific resistances, 2ARPdAg and 2ARPdAu (sample area A times resistance R), and spin-flip probabilities δPdAg and δPdAu for Pd/Ag and Pd/Au interfaces with current perpendicular to the interfaces. 2ARPdAg=0.7±0.15 fωm ² and 2ARPdAu=0.45±0.15 fωm ² are smaller than our revised estimate of 2ARPdCu=0.85±0.15 fωm ², and lie further from no-free-parameter calculations. Our estimates of δPdAg=0.15±0.08 and δPdAg=0.08±0.08 are less than our prior estimate of δPdCu~0.24.
