Summary

CRITICAL VALUES OF THEDENSITY OF EXTRINSIC CURRENT OF THE RIGID JOSEPHSON VORTEX CHAIN DEPINNING IN A LONG JOSEPHSON JUNCTION WERE CALCULATED IN TERMS OF THE PERTURBATION THEORY. A MINIMUM VALUE OF THE CURRENT DENSITY WERE ESTIMATED WHICH WOULD PERMIT THE CHAIN FREE MOTION THROUGH THE TRANSITION ON DISSIPATION. THE DEPENDENCE OF CRITICAL CURRENT ON EXTERNAL MAGNETIC FIELD, H, IS MEASURED FOR LONG JOSEPHSON JUNCTIONS NB-NBO(X)-PB WITH ARTIFICIAL SPATIALLY PERIODIC HETEROGENEITIES OF DIELECTRICBARRIER. FOR MULTIPLE VALUES OF H, THE CRITICAL CURRENT/H CURVE IS FOUND TO DISPLAY SOME PEAKS WHICH, ACCORDING TO THE THEORY, ARE RESPONSIBLE FOR AN INCREASE IN THE FORCE OF JOSEPHSON VORTEX PINNING BY THE BARRIER HETEROGENEITIES WHEN THE SPATIAL PERIODS OF THE VORTEX CHAIN AND THE HETEROGENEITY LATTICE ARE COMMENSURATE.
