Spin-polarized tunneling was used to study exchange effects as a function of spin-orbit scattering rate at the surface of thin Al films, each covered with a submonolayer of Gd. The spin-orbit scattering rate was controlled by the deposition of a Pt layer on the side of the Al film opposite that covered with Gd. At sufficient Pt coverages, the Zeeman splitting of the conduction electrons is washed out, but the magnitude of the polarization is unchanged. Furthermore, polarization of the same magnitude is observed in both the superconducting and normal state. These results are understood in terms of the dependence of the conduction-electron spin susceptibility on the spin-orbit scattering rate.
