Spin-orbit interaction in magnetic quantum well states of Ni/W(110) — •Andreas Nuber1, Hendrik Bentmann1, and Friedrich Reinert1,2 — 1Experimentelle Physik VII, Universität Würzburg, Germany — 2Karlsruhe Institute of Technology, 76021 Karlsruhe, Germany
Nickel is a model system for ferromagnetism with an exchange splitting of the minority and majority bulk band structure of approximately 0.3 eV. Growing thin films of Nickel on a W(110) substrate results in the formation of quantum well states (QWS) within the film. Due to the non-perfect confinement, the wave function of the QWS extend into the first monolayers of the tungsten substrate leading to an interaction with the large potential gradient of the W atoms. We present a high resolution ARUPS study of the electronic structure of thin Nickel films on W(110) which is influenced by the spin-orbit interaction mediated by the substrate and the exchange interaction of Nickel.
