Model for superconducting current in HTSC: How to calculate the maximum intrinsic values

Summary In order to explain the HTSC electrical density values, the authors propose a new original model for these new superconductors, introducing the parameterSc, given by the ratio between the coherence distance ξ₀ and the lattice constant λ₁. The value ofSc is less than 1 in HTSC and higher than 1 in normal s.c. In HTSC the pair electron transport mechanism became different than in other s.c., in which a wave function linear coherence is established. A Josephson intrinsic electrical conduction mechanism is established. The HTSC behaves like a good diamagnetic material but a bad superconductor.
