✦ Synopsis

It is shown, within a simple model calculation, that the critical current density of an S/N/S junction in a high paralel magnetic field decays exponentially. The comparison of the theoretical results with experimental data for the Pb/Cd/Pb junction and YBCO films is given.

High critical current densities at the level of magnetic field needed for specific operation, is an important prerequisit for the application of all kinds of superconductors. The discovery of the high Tc superconductors created enormous new hopes for a much broader breakthrough for superconductivity
