Interplay of spin-orbit and exchange interaction in ultrathin Ni films on W(110) — •Pascal Jona Grenz¹, Philipp Eickholt¹, Koji Miyamoto², Eike Schwier², Taichi Okuda², and Markus Donath¹ — ¹Institute of Physics, Westfälische-Wilhelms-Universität Münster, Germany — ²Hiroshima Synchrotron Radiation Center, Japan

Ferromagnetic adsorbates on W(110) are prototypical systems for studying the influence of spin-orbit and exchange interaction on electronic states. We investigated ultrathin Ni films on W(110) with spin- and angle-resolved photoemission with particular emphasis on (i) the influence of the Ni adsorbates on the Dirac-cone-like surface state of W(110), (ii) the spin dependence of electronic states at the interface between Ni and W, and (iii) the appearance of ferromagnetic order in the Ni overlayer. We will discuss our results in relation to similar systems reported in literature, Fe/W(110) and Co/W(110) [1,2].
