However, so far the spin-dependence is in the diffusive approach included only for limiting cases. Here, we derive the fully spin-dependent boundary condition completing the Usadel equation and the circuit theory. Both, material specific spin-degrees of freedom and spin-dependent interface effects, i.e. spin-mixing and polarization of the transmission coefficients are treated exactly. This opens the road to accurately describe a completely new class of mesoscopic circuits including materials with strong intrinsic magnetic structure. We also discuss several experimentally relevant cases like the tunnel limit, a ferromagnetic insulator with arbitrarily strong magnetization and the limit of small spin-mixing.</dcterms:abstract> <dcterms:issued>2015</dcterms:issued> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/31007"/> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2015-05-21T09:09:35Z</dc:date> </rdf:Description> </rdf:RDF>
