Thin film growth characterization of a mulitpurpose physical vapor deposition apparatus with the goal of investigating tailored perpendicular magnetic anisotropy systems — •Florian Ott, Christian Janzen, Arne Schröder, and Arno Ehresmann — Institute of Physics, University of Kassel, D-34132 Kassel

In recent years, systems of multilayered (ML) magnetic thin films consisting of ferromagnetic transition metals (TM) with noble metallic spacers displaying perpendicular magnetic anisotropy (PMA) have gained increased interest for applications in magnetic particle transport [1], controlled domain movement [1,2] and sensor technologies [3]. These TM-based PMA systems may rely on the precise modulation of layer growth additionally to the already very low thickness requirements [1]. As a result, a precise control of the growth conditions is necessary in order to produce these systems. This work focuses on the characterization of growth conditions and parameters inside a multipurpose physical vapor deposition (PVD) apparatus with the ultimate goal of creating and investigating engineered TM-based PMA systems.
