      abstract     = {We study the influence of the interface quality of
                      Pt/Y3Fe5O12(111) hybrids on their spin Hall
                      magnetoresistance. This is achieved by exposing
                      Y3Fe5O12(111) single crystal substrates to different
                      well-defined surface treatments prior to the Pt deposition.
                      The quality of the Y3Fe5O12(YIG) surface, the Pt/YIG
                      interface and the Pt layer is monitored in-situ by
                      reflection high-energy electron diffrac- tion and Auger
                      electron spectroscopy as well as ex-situ by atomic force
                      microscopy and X-ray diffraction. To identify the impact of
                      the different surface treatments on the spin Hall
                      magnetoresis- tance, angle-dependent magnetoresistance
                      measurements are carried out at room temperature. The
                      largest spin Hall magnetoresistance is found in Pt/YIG
                      fabricated by a two-step surface treatment consisting of a
                      “piranha” etch process followed by an annealing step at
                      500􏰀C in pure oxygen atmo- sphere. Our data suggest that
                      the small spin Hall magnetoresistance in Pt/YIG without any
                      surface treatments of the YIG substrate prior to Pt
                      deposition is caused by a considerable carbon agglomera-
                      tion at the Y3Fe5O12 surface.},
