By using a combination of first-order reversal curve measurements, magnetic x-ray microscopy, and micromagnetic simulations we elucidate the microscopic origins of the switching field distributions that arise from the introduction of antidot lattices into out-of-plane magnetized GdFe thin films. Depending on the geometric parameters of the antidot lattice we find two regimes with different magnetization reversal processes. For small antidots, the reversal process is dominated by the exchange interaction and domain wall pinning at the antidots drives up the coercivity of the system. On the other hand, for large antidots the dipolar interaction is dominating which leads to fragmentation of the system into very small domains that can be envisaged as a basis for a bit patterned media.</dcterms:abstract> <dc:creator>Träger, Nick</dc:creator> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-05-11T10:33:26Z</dc:date> <dc:contributor>Ziemann, Paul</dc:contributor> <bibo:uri rdf:resource="https://kops.uni-konstanz.de/handle/123456789/33881"/> <dcterms:title>Geometric control of the magnetization reversal in antidot lattices with perpendicular magnetic anisotropy</dcterms:title> <dcterms:rights rdf:resource="http://nbn-resolving.de/urn:nbn:de:bsz:352-20150914100631302-4485392-8"/> <dc:contributor>Goering, Eberhard J.</dc:contributor> <dc:contributor>Nowak, Ulrich</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2016-05-11T10:33:26Z</dcterms:available> <dc:creator>Skripnik, Maxim</dc:creator> <dc:creator>Ziemann, Paul</dc:creator> </rdf:Description> </rdf:RDF>
