We study theoretically and experimentally the influence of pancake vortices on motion of the Josephson vortex lattice in layered high-temperature superconductors. Mobility of the Josephson vortices in layered superconductors is strongly suppressed by a small amount of pancake-vortex stacks. Moving Josephson vortex lattice forces oscillating zigzag deformation of the pancake-vortex stacks contributing to damping. The salient feature of this contribution is its nonmonotonic dependence on the…

TLDR
The high- frequencies excitations of the Josephson loops can be utilized in future design of powerful emitters, tunable filters and waveguides of high-frequency electromagnetic radiation, thereby pushing forward the much needed Terahertz technology.

Decoration of Josephson vortices by pancake vortices in Bi 2 Sr 2 CaCu 2 O 8 + d
Josephson vortices are imaged magneto-optically due to their decoration with pancake vortices in ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+d}$ single crystals.
Vortices in layered superconductors with Josephson coupling.
TLDR
Strongly anisotropic layered superconductors are considered within the Lawrence-Doniach model and the angular dependence of the torque is evaluated for tilted, combined, and parallel lattices, which allows one to experimentally distinguish these phases.
Josephson vortices and solitons inside pancake vortex lattice in layered superconductors
In very anisotropic layered superconductors a tilted magnetic field generates crossing vortex lattices of pancake and Josephson vortices (JV's). We study the properties of an isolated JV in the

TLDR
A microstructure is realized which leads to very strong high-temperature flux pinning in YBa and Cu crystals, and causes a considerable enlargement of the irreversibility region in the H-T plane.

TLDR
It is demonstrated that the observed enhanced pinning of pancakes can be explained in terms of the recoupling of the layers by the columnar defects, which effectively increase the interlayer Josephson coupling by suppressing thermal fluctuations of pancakes positions.
