- Title
Nonsinusoidal Current–Phase Relation in SFS Josephson Junctions.

- Abstract
Various types of current–phase relation I(φ) in superconductor–ferromagnet–superconductor (SFS) point contacts and planar double-barrier junctions are studied within the quasi-classical theory in the limit of thin diffusive ferromagnetic interlayers. The physical mechanisms leading to highly nontrivial I(φ) dependence are identified by studying the spectral supercurrent density. These mechanisms are also responsible for the 0–π transition in SFS Josephson junctions. © 2002 MAIK “Nauka / Interperiodica”.
