Paper Abstract

We consider the Josephson vortex flow in layered superconductors in the presence of the transport DC current perpendicular to the layers and high magnetic field parallel to the layers. Moving vortex lattice induces the radiation from the edge of the crystal into the dielectric. We derive radiation power for moving rectangular and triangular lattice. We estimate corresponding radiation power for Bi-based cuprate superconductor when the magnetic field of order of one tesla is applied and the radiation frequency is in THz interval. We show qualitatively that radiation power for lattice disordered along the c-axis is weaker than that for regular lattice. We estimate the heat flow which in cuprate crystals is determined mainly by the nodal quasiparticles.
