Because of the spin torque effect such a quasiparticle in a potential well is excited by an ac current leading to a dip in the depinning field at resonance for current densities as low as 2 x 10 power 10 A/m power 2. Independently the resonance frequencies of transverse walls and vortex walls are determined from the dc voltage that develops due to a rectifying effect of the resonant domain wall oscillation. The dependence on the injected current density reveals a strongly nonharmonic oscillation.</dcterms:abstract> <dc:creator>Krzyk, Stephen</dc:creator> <dc:creator>Bedau, Daniel</dc:creator> <dc:format>application/pdf</dc:format> <dc:contributor>Kläui, Mathias</dc:contributor> <dc:contributor>Rüdiger, Ulrich</dc:contributor> <dcterms:title>Detection of current-induced resonance of geometrically confined domain walls</dcterms:title> <dcterms:available rdf:datatype="">2011-03-24T14:50:22Z</dcterms:available> <dc:creator>Vila, Laurent</dc:creator> <bibo:uri rdf:resource=""/> <dc:date rdf:datatype="">2011-03-24T14:50:22Z</dc:date> <dc:creator>Rüdiger, Ulrich</dc:creator> <dc:creator>Kläui, Mathias</dc:creator> <dc:creator>Faini, Giancarlo</dc:creator> <dcterms:rights rdf:resource=""/> <dc:contributor>Faini, Giancarlo</dc:contributor> <dc:contributor>Krzyk, Stephen</dc:contributor> </rdf:Description> </rdf:RDF>
