Lernziel:
After successfully completing this module the students will have a good overview of both fundamentals and current research in the fields of surface science, electronic structure and magnetism in reduced dimensions, and spintronics. A focus of this lecture will be put on magnetic atoms, nanostructures, and films on single crystal surfaces. The students will be able to understand experimental sample preparation procedures as well as experimental techniques of low-temperature physics and different surface science characterization tools, such as for instance spin-sensitive scanning probe methods. They will be able to identify different magnetic interactions responsible for the emergence of magnetic order and will be able to explain different theoretical tools for an understanding and prediction of complex magnetic states including their dynamics. Finally, they will be able to connect the topics to current research activities like, e.g., topological materials, magnetic skyrmions, and skyrmion-superconductor hybrid sytems.
Students will be eligible to perform the Nanostrukturphysik II - Vertiefungspraktikum either during the module or anytime afterwards.
