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 a universal function of the phase difference Ω between adjacent layers, while a simple Josephson sinusoidal dependence on Ω is valid only at rather low temperature T4,Tev the 3D-2D crossover temperature.
