In an external magnetic field these highly disordered magnetic systems have a domain structure which consists of fractal domains with sizes on a broad range length scales. We focus on the dynamics of these systems during the relaxation from a long-range ordered initial state to the disordered fractal-domain state after applying an external magnetic field. The equilibrium state with applied field consists of fractal domains with a size distribution which follows a power law with an exponential cutoff. The dynamics of the systems can be understood as a growth process of this fractal-domain state in such a way that the equilibrium distribution of domains develops during time. Following these ideas quantitatively we derive a simple description of the time dependence of the order parameter. The agreement with simulations is excellent.</dcterms:abstract> <dc:creator>Nowak, Ulrich</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:55:04Z</dcterms:available> <dc:creator>Esser, J.</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/5340"/> <dc:format>application/pdf</dc:format> <dc:contributor>Esser, J.</dc:contributor> <dc:contributor>Nowak, Ulrich</dc:contributor> <dcterms:bibliographicCitation>First publ. in: Physica A: Statistical Mechanics and its Applications 232 (1996), 1-2, pp. 40-50</dcterms:bibliographicCitation> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103416863-3868037-7"/> <dc:contributor>Usadel, Klaus-Dieter</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T14:55:04Z</dc:date> <dc:language>eng</dc:language> <dcterms:issued>1996</dcterms:issued> <dc:creator>Usadel, Klaus-Dieter</dc:creator> <dcterms:title>Dynamics of domains in diluted antiferromagnets</dcterms:title> <dc:rights>deposit-license</dc:rights> </rdf:Description> </rdf:RDF>
