EXCITATION OF PLASMA-OSCILLATIONS DURING THE MOTION OF JOSEPHSON VORTICES IN LAYERED SUPERCONDUCTORS

The electric and magnetic fields arising during uniform motion of a vo rtex lattice in a magnetic field oriented parallel to the conducting l ayers are calculated in an exactly solvable model. For low temperature s and high velocities of the lattice, features due to the excitation o f plasma oscillations of the superconducting electrons appear in the c urrent-voltage characteristic. Peaks associated with plasmon excitatio n and the Cherenkov effect are present in the radiation spectrum. (C) 1997 American Institute of Physics. [S0021-3640(97)01224-3].
