The fabrication of multilayer Josephson structures based on high-T C thin films is reported. YBa2Cu3Ox thin films are prepared by in-situ rf magnetron sputtering. SIS and SNS edge junctions were produced. In the first case an intermediate layer withstands the high temperature process of the upper HT

β¦ Synopsis
It is shown that the magnon mechanism proposed by Goddard and co-workers to explain high-temperature superconductivity m oxidized cuprates can also account for such superconductivity in both oxidized barium bismuthate and the electron superconductors based on neodynium cuprate. The specific and characteristic electronic structure required for the operanon of the magnon mechanism naturally accounts for why only a small number of basic types of high-temperature superconductors are currently known. This mechanism can readily explain the effects of doping cuprate superconductors with both magnetic and non-magnetic

Convergent beam electron diffraction (CBED) is a powerful technique for symmetry study of crystal. It has widespread application in physics and material sciences, as demonstrated in a recent superconducting oxide study. Using this technique, we have studied Ba-La-Cu-O superconductors with a transiti
