Realization of a new Magnetic Scanning X-ray Microscope and Investigation of Landau Structures under Pulsed Field Excitation

Langbeschreibung
Magnetic nanostructures in thin films and their behavior have seen a drastic increase in scientific interest in the last decades. Similarly, X-ray microscopy has moved into the spotlight since the turn of the century. This thesis combines both topics with the investigation of magnetic vortex structures under pulsed field excitation using both micromagnetic simulations and time resolved magnetic X-ray microscopy. This allowed the observation of vortex core polarization switches with
Markus Weigand, born 1980 in Lohr am Main, studied at the University Würzburg first nanostructure technology (intermediate diploma) and then physics, receiving his diploma degree in 2006. Main focus of his thesis in the group of Prof. Eberhard Umbach was resonant inelastic x-ray scattering (RIXS) of both cobalt nanoparticles as well as ammonia in aqueous solution. In 2007 he joined the MPI for Intelligent Systems (formerly Metals Reseach) for a PhD thesis focusing on time resolved x-ray microscopy of magnetic nanostructures, and starting 2009 took over the operation of a new X-ray microscope operating at the Helmholtz-Zentrum Berlin. He was awarded his Dr. rer. nat. degree from the University of Stuttgart in 2015.
