Abstract: | The maximal supercurrent Im of a short Josephson junction formed by an edge contact of two superconducting films is calculated for the case where the junction is placed in a periodic field produced by a chain of magnetic nanoparticles. The commensurability effects occurring when the magnetic flux of a homogeneous external field H0 through an elementary cell is equal to an integral number of magnetic flux quanta Φ0 are considered. The effects give rise to additional maxima in the Im(H0) dependence. |
