First, ferromagnetism was predicted for dilute magnetic doping. In comprehensive investigation of ZnO:Co thin films based on the combined measurement of macroscopic and microscopic properties, we find no evidence for carrier-mediated itinerant ferromagnetism. Phase-pure, crystallographically excellent ZnO:Co is uniformly paramagnetic. Superparamagnetism arises when phase separation or defect formation occurs, due to nanometer-sized metallic precipitates. Other compounds like ZnO:(Li,Ni) and ZnO:Cu do not exhibit indication of ferromagnetism. Second, its small spin-orbit coupling and correspondingly large spin coherence length makes ZnO suitable for transporting or manipulating spins in spintronic devices. From optical pump/optical probe experiments, we find a spin dephasing time of the order of 15 ns at low temperatures which we attribute to electrons bound to Al donors. In all-electrical magnetotransport measurements, we successfully create and detect a spin-polarized ensemble of electrons and transport this spin information across several nanometers. We derive a spin lifetime of 2.6 ns for these itinerant spins at low temperatures, corresponding well to results from an electrical pump/optical probe experiment.</dcterms:abstract> <dc:contributor>Althammer, Matthias</dc:contributor> <dc:contributor>Karrer-Müller, Eva-Maria</dc:contributor> <dcterms:isPartOf rdf:resource=""/> <dcterms:rights rdf:resource=""/> <dc:contributor>Weier, Christian</dc:contributor> <dspace:hasBitstream rdf:resource=""/> <dc:creator>Althammer, Matthias</dc:creator> <dc:contributor>Gönnenwein, Sebastian T.B.</dc:contributor> <dc:date rdf:datatype="">2021-05-28T08:08:31Z</dc:date> <dcterms:title>Zinc oxide : From dilute magnetic doping to spin transport</dcterms:title> <dc:creator>Senn, Konrad</dc:creator> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:creator>Nielsen, Karl-Wilhelm</dc:creator> <dc:contributor>Nielsen, Karl-Wilhelm</dc:contributor> <dcterms:available rdf:datatype="">2021-05-28T08:08:31Z</dcterms:available> <bibo:uri rdf:resource=""/> <dc:contributor>Opel, Matthias</dc:contributor> </rdf:Description> </rdf:RDF>
