Dislocations and vortex structure were observed in thin BSCCO single crystals by the method of transmission electron microscopy. The vortex structure was visualized by a high-resolution technique of decoration with very small ferromagnetic particles. Individual dislocations oriented perpendicular to the vortices do not destroy the long-range order in the vortex lattice. A weak attractive interaction between the dislocations and vortices, which does not depend on the type of dislocations, was observed. © 7995 American Institute of Physics.
