Current-phase relation in layered cuprates
Genenko Yu.A., Medvedev Yu.V., Shuster G.V.
The influence of interlayer tunneling in layered superconducting (SC) medium on the intralayer SC is shown to be essential in strongly anisotropic cuprates. Josephson-like transverse current is found to be some universal function of the phase difference Ω between adjacent layers while simple Josephson sinusoidal dependence on Ω is valid only at rather low temperatures Τ <ζ Tct, 3D-2D crossover temperature.
