abstract = {Harnessing spin-orbit coupling for the manipulation of
spins and magnetization via electric charge currents is the
key objective of spin-orbitronics. Towards this end
ferromagnetic materials are combined with nonmagnetic
materials with strong spin-orbit coupling (typically
involving heavy elements). However, many of the nominally
nonmagnetic materials are highly susceptible to magnetic
proximity effects, and the role of induced moments for spin
transport has been controversial. Here we demonstrate that
for Pt and Pd increased induced magnetic moments are
correlated with strongly reduced spin-Hall conductivities.
This observation finds an intuitive explanation in the
development of a spin splitting of the chemical potential
and the energy dependence of the intrinsic spin-Hall effect
determined by first-principles calculations. This work
provides simple guidance towards the optimization of spin
current efficiencies for devices based on spin-orbit
coupling phenomena.},
