  The occurrence of Spin-Hall Magnetoresistance (SMR) in platinum (Pt) on top
of yttrium iron garnet (YIG) has been investigated, for both in-plane and
out-of-plane applied magnetic fields and for different Pt thicknesses [3, 4, 8
and 35nm]. Our experiments show that the SMR signal directly depends on the
in-plane and out-of-plane magnetization directions of the YIG. This confirms
the theoretical description, where the SMR occurs due to the interplay of
spin-orbit interaction in the Pt and spin-mixing at the YIG/Pt interface.
Additionally, the sensitivity of the SMR and spin pumping signals on the YIG/Pt
interface conditions is shown by comparing two different deposition techniques
(e-beam evaporation and dc sputtering).
