“…This Eu(4f) -Pt(5d) coupling is the primary reason for the en-hanced magnetic anisotropy of this mid-gap conducting magnetic state. In addition, EuO may also exhibit strong d-f hybridization and spin-orbit coupling [43][44][45][46] . Such effect will be particularly strong at the surfaces or interfaces due to symmetry breaking.…”

We report proximity effects of spin-orbit coupling in EuO1−x films capped with a Pt overlayer. Transport measurements suggest that current flows along a conducting channel at the interface between the Pt and EuO. The temperature dependence of the resistivity picks up the critical behaviors of EuO, i.e., the metal-to-insulator transition. We also find an unusual enhancement of the magnetic anisotropy in this structure from its bulk value which results from strong spin-orbit coupling across the Pt/EuO1−x interface.

“…The moment reduction in thin EuO 1-x films cannot thus be explained by a reduction of the g-factor. Another factor to consider is that the 4f orbitals of EuO have been reported to be susceptible to pinning from the local crystalline environment [22,23]; this could cause a reduction of the moment. However, such surface pinning would result in a strongly non-linear thickness dependence of the average moment, with a functionality of the type given by Eq.…”
