Using the quantum circuit theory, we obtain the phase diagram of 0 and pi Josephson couplings for F-c being an insulator-ferromagnet-insulator (IFI) double barrier junction or an IFNFI structure (where N indicates a normal-metal layer). Compared to a simple SFS structure, we find that the width of the transition, defined by the interval of exchange fields in which a 0-pi transition is possible, is increased by insulating barriers at the interfaces and also by the presence of the additional N layer. The widest transition is found for symmetric F-c structures. The symmetric SIFNFIS presents the most favorable condition to detect the temperature-induced 0-pi transition with a relative width, which is five times larger than that of the corresponding simple SFS structure.</dcterms:abstract> <dcterms:bibliographicCitation>Publ. in: Physical Review B 78 (2008), 214518</dcterms:bibliographicCitation> <dc:creator>Zareyan, Malek</dc:creator> <dc:creator>Belzig, Wolfgang</dc:creator> <dcterms:title>Width of the 0-pi phase transition in diffusive magnetic Josephson junctions</dcterms:title> </rdf:Description> </rdf:RDF>
