Abstract
A method of producing a high temperature superconductor Josephson element and an improved SNS weak link barrier element is provided. A YBaCuO superconducting electrode film is deposited on a substrate at a temperature of approximately 800.degree. C. A weak link barrier layer of a nonsuperconducting film of N--YBaCuO is deposited over the electrode at a temperature range of 520.degree. C. to 540.degree. C. at a lower deposition rate. Subsequently, a superconducting counter-electrode film layer of YBaCuO is deposited over the weak link barrier layer at approximately 800.degree. C. The weak link barrier layer has a thickness of approximately 50 .ANG. and the SNS element can be constructed to provide an edge geometry junction.
