SIMULTANEOUS OBSERVATION OF VORTICES AND DISLOCATIONS IN THIN BSCCO-(2212) SINGLE-CRYSTALS

Dislocations and vortex structure were observed in thin BSCCO single c rystals 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 orien ted perpendicular to the vortices do not destroy the long-range order in the vortex lattice. A weak attractive interaction between the dislo cations and vortices, which does not depend on the type of dislocation s, was observed. (C) 1995 American Institute of Physics.
