Josephson penetration depth
In superconductivity, Josephson penetration depth characterizes the typical length on which an externally-applied magnetic field penetrates into the long Josephson junction. Josephson penetration depth is usually denoted as λJ and is given by the following expression (in SI):
Additional recommended knowledge
where Φ0 is the magnetic flux quantum, jc is the critical current density (A / cm2), and d' characterizes the inductance of the superconducting electrodes
where dI is the thickness of the Josephson barrier (usually insulator), d1,2 are the thicknesses of superconducting electrodes, and λ1,2 are their London penetration depths.
