Based on a spin-dependent Boltzmann-Langevin equation, we develop a semiclassical theory of charge and spin currents and the correlations of the currents fluctuations. In the three terminal system, we show that current fluctuations are strongly affected by the spin-flip scattering in the normal metal and the spin polarizations of the terminals, which may point in different directions. We analyze the dependence of the shot noise and the cross-correlations on the spin-flip scattering rate in the full range of the spin polarizations and for different magnetic configurations. Our result demonstrate that noise measurements in multi-terminal devices allow to determine the spin-flip scattering rate by changing the polarizations of ferromagnetic terminals.</dcterms:abstract> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:54:51Z</dcterms:available> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/9247"/> <dc:creator>Belzig, Wolfgang</dc:creator> <dc:format>application/pdf</dc:format> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:54:51Z</dc:date> <dcterms:issued>2005</dcterms:issued> <dc:creator>Zareyan, Malek</dc:creator> <dcterms:bibliographicCitation>First publ. in: Physical Review B 71 (2005), Article 184403</dcterms:bibliographicCitation> <dcterms:rights rdf:resource="https://creativecommons.org/licenses/by-nc-nd/2.0/legalcode"/> <dcterms:title>Semiclassical theory of spin-polarized shot noise in mesoscopic diffusive conductors</dcterms:title> <dc:contributor>Belzig, Wolfgang</dc:contributor> <dc:contributor>Zareyan, Malek</dc:contributor> <dc:language>eng</dc:language> </rdf:Description> </rdf:RDF>
