The invention concerns a layered arrangement comprising at least one layer based on a high-temperature superconductive material with at least one unit cell having a CuO plane, the layer being connected to a non-supeconductive layer. A modified interface layer is provided between the two layers. Alternatively, at least one of the contacting layers can be modified in the interface region. Modification can be brought about by doping with metallic ions or implantation.

Layered arrangement and component containing the latter

The invention relates to a series of layers containing at least one layer on the basis of REBa,CU,O7,or with a comparable crystallographic structure, wherein said layer is connected to a non-superconductive layer. The only material chosen for the non-superconductive layer is material containing atomic components which are chemically compatible with the superconductive material of the high temperature superconductive layer. Such a series of layers enables a multilayer system or also a cryogenic component, e.g. a Josephson contact, to be formed.
