We use time-resolved X-ray microscopy to dynamically image the chirality-switching process and perform micromagnetic simulations to deduce the switching details from time-resolved snapshots. We find experimentally that the switching occurs within less than 4 ns and is observed in all samples with ring widths ranging from 0.5 μm to 2 μm, ring diameters between 2 μm and 5 μm, and a thickness of 30 nm, where a vortex domain wall is present in the magnetic onion state of the ring. From the magnetic contrast in the time-resolved images, we can identify effects of thermal activation, which plays a role for the switching process. Moreover, we find that the process is highly reproducible so that the domain wall chirality can be set with high fidelity.</dcterms:abstract> <dc:creator>Tyliszczak, Tolek</dc:creator> <dcterms:issued>2015</dcterms:issued> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-06-24T13:30:24Z</dc:date> <dc:contributor>Mawass, Mohamad-Assaad</dc:contributor> <dc:contributor>Gliga, Sebastian</dc:contributor> <dc:creator>Bisig, Andre</dc:creator> <dc:contributor>Bisig, Andre</dc:contributor> </rdf:Description> </rdf:RDF>
