Abstract
Experimental observation of the strong influence of an array of ferromagnetic nanodots on the critical current of a short overlap Josephson junction is reported. Pronounced commensurability effects are detected due to the presence of the additional peaks in the magnetic-field-induced diffraction pattern. The changes in the Fraunhofer pattern of the Josephson junctions are accounted for by the formation of Abrikosov vortices trapped in the electrodes which induce a phase inhomogeneity in the junction area.
