Abstract (English)

In the framework of this thesis the magnetic ground state of hexagonally shaped ferromagnetic nanotubes and ways to manipulate this state are investigated in detail. The nanotubes consist of permalloy with possible additional layers such as aluminum oxide. Utilizing the anisotropic magnetoresistance effect (AMR) we find very stable vortex ground states that are independent of the geometry of the ...

Im Rahmen dieser Arbeit wird der magnetische Grundzustand von magnetischen Nanotubes im Detail untersucht. Die Nanotubes bestehen aus Permalloy und können zusätzliche Schichten, wie zum Beispiel Aluminiumoxid, aufweisen. Durch Anwendung des anisotropen Magnetowiderstands (AMR) werden sehr stabile Vortex Grundzustände gefunden. Diese sind unabhängig von der Geometrie des Nanotubes. Als Grund wird ...
