NONLOCAL JOSEPHSON ELECTRODYNAMICS OF PLATES OF FINITE THICKNESS

A nonlocal integrodifferentical equation describing the electrodynamic s of a Josephson junction between superconductors of finite thickness in the direction of the magnetic field is derived. It is shown that th e interaction of kinks always exhibits long-range power-law asymptotic behavior, which can strongly influence the motion of vortices in and the current-voltage characteristic of even a thick contact. The spectr um of low-amplitude excitations is studied. (C) 1997 American Institut e of Physics.
