- W2394773487 abstract "Ultrathin Pt films grown on insulating ferrimagnetic $mathrm{CoF}{mathrm{e}}_{2}{mathrm{O}}_{4}$ (111) epitaxial films display a magnetoresistance upon rotating the magnetization of the magnetic layer. We report here x-ray magnetic circular dichroism (XMCD) recorded at Pt-${L}_{2,3}$ and Pt-${M}_{3}$ edges. The results indicate that the Pt magnetic moment, if any, is below the detection limit ($<0.001phantom{rule{0.16em}{0ex}}{ensuremath{mu}}_{mathrm{B}}/mathrm{Pt}$), thus strongly favoring the view that the presence of $mathrm{CoF}{mathrm{e}}_{2}{mathrm{O}}_{4}$ does not induce the formation of magnetic moments in Pt. Therefore, the observed magnetoresistance cannot be attributed to some sort of proximity-induced magnetic moments at Pt ions and subsequent magnetic-field dependent scattering. It thus follows that either bulk (spin Hall and inverse spin Hall effects) or interface (Rashba) spin-orbit related effects dominate the observed magnetoresistance. Furthermore, comparison of bulk magnetization and XMCD data at (Fe,Co)-${L}_{2,3}$ edges suggests the presence of some spin disorder in the $mathrm{CoF}{mathrm{e}}_{2}{mathrm{O}}_{4}$ layer which may be relevant for the observed anomalous nonsaturating field dependence of spin Hall magnetoresistance." @default.
