Nonsinusoidal current-phase relation in SFS Josephson junctions
arXiv:cond-mat/0204568 · doi:10.1134/1.1500729 10.1134/1.1517391
Abstract
Various types of the current-phase relation I(phi) in superconductor-ferromagnet-superconductor (SFS) point contacts and planar double-barrier junctions are studied within the quasiclassical theory in the limit of thin diffusive ferromagnetic interlayers. The physical mechanisms leading to highly nontrivial I(phi) dependence are identified by studying the spectral supercurrent density. These mechanisms are also responsible for the 0-pi transition in SFS Josephson junctions.
