Our studies show that the vortex core becomes thermally unstable with increasing temperature, acting like a superparamagnetic system. On time scales where the vortex core remains within one of the metastable states it still has a stronger temperature dependence than the magnetization far away in the bulk of a domain.</dcterms:abstract> <dcterms:issued>2006</dcterms:issued> <dc:language>eng</dc:language> <dc:date rdf:datatype="">2011-03-24T17:54:04Z</dc:date> <dc:contributor>Nowak, Ulrich</dc:contributor> <dc:contributor>Wieser, Robert</dc:contributor> <dc:creator>Nowak, Ulrich</dc:creator> <dc:rights>deposit-license</dc:rights> <bibo:uri rdf:resource=""/> <dc:format>application/pdf</dc:format> </rdf:Description> </rdf:RDF>
