Title: Superconductor structure with glass substrate and high-temperature superconductor deposited thereon, current limiter device having the superconductor structure and process for producing the structure

Abstract: A superconductor structure inclludes a substrate made from a temperature-resistant glass material, a buffer layer which has been deposited on the substrate, and a layer of a metal oxide high T.sub.c superconductor material that has been deposited thereon. A glass material with a coefficient of thermal expansion of over 6.multidot.10.sup.-6 K.sup.-1 and a transformation temperature of over 550.degree. C. is to be provided. At least a deposition process in which a maximum temperature is at most 100 K higher than the transformation temperature of the glass material is selected for the production of the structure. A current limiter device is also provided.
