Abstract
Attractive interaction between pancake-vortex lines (PVLs) and
Josephson vortices (JVs) in layered high-temperature superconductors is
attributed to the local polarization of PVL at a crossing point by the
currents circulating around the JV. To verify this mechanism we measured the
Josephson flux-flow resistance in Bi-2212 stacked structures in a presence of
PVLs for two cases, when PVLs are free and when they are trapped by columnar
defects that highly suppress their local polarization. We found that the
trapping PVLs by columnar defects (CDs) significantly eliminates interaction
between PVLs and JVs. That observation strongly supports the local PVL
polarization as a mechanism for their attractive interaction with JVs.
