While the magnetocrystalline anisotropy of bulk iron suggests superparamagnetic behavior in this size range, ferromagnetically blocked particles are also found at all sizes. Spontaneous transitions from the blocked state to the superparamagnetic state are observed in single particles and suggest that the enhanced magnetic energy barriers in the ferromagnetic particles are due to metastable, structurally excited states with unexpected life times.</dcterms:abstract> <dc:contributor>Nolting, Frithjof</dc:contributor> <dc:contributor>Nowak, Ulrich</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-05-23T11:53:32Z</dc:date> </rdf:Description> </rdf:RDF>
