摘要： A wet-chemical method for producing strip-shaped high-temperature superconductors with a substrate, optionally with a buffer layer and with a high-temperature superconductive layer is improved by increasing the texturing and the layer thickness of the high-temperature superconductive layer. To this end, precursor solutions are applied in layers to the substrate, of which the first is low in fluorine or does not contain fluorine, and the following have a fluorine concentration that increases with each layer.

摘要： A band-shaped high-temperature superconductor (HTSL) with high critical current density can be produced economically in a wet-chemical process. In the process, a first precursor solution is applied to a carrier, dried, and annealed. Additional precursor solutions may then be applied, with the first precursor solution contain little or no pinning centers, and any subsequent precursor solutions contains a higher concentration of pinning centers than the first precursor solutions.

摘要： The invention relates to a method for coating shaped bodies made of a superconducting material based on (Y/SE)BaCuO. The invention is characterized in that a coating consisting of a coating material is applied to at least one part of a surface of the shaped body, whereby the coating material at least partially melts at a lower temperature than that of the material of the shaped body and/or is flowable at a lower temperature than that of said material. The shaped body with the applied coating material is heated to a temperature at which the material of the shaped body does not yet melt and/or is not yet flowable, however at which the coating material is at least partially melted thereon and/or is in a flowable state. In addition, at least one part of the area of the shaped body located near the surface is modified at said temperature and/or during a successive cooling, and the shaped body treated in such a manner is enriched with oxygen during cooling and/or during a successive heat treatment, whereby the modification contributes to the increase in remanent induction and/or to the critical current density of the shaped body enriched with oxygen. The invention also relates to a shaped body made of a superconducting material which is based on (Y/SE)BaCuO and which can be obtained by using the above-mentioned method. Said superconducting material contains at least one rare-earth element selected from the group of Y, La, Ce, Pr, Nd, Eu, Gd, Tb, Dy, Ho, Er Tm, Yb and Lu and comprises a maximal value of remenant induction of at least 1100 mT at 77K and O T.
