Abstract

The invention relates to a product having a substrate of a partially stabilized zirconium oxide and a buffer layer of a fully stabilized zirconium oxide. In this case, the substrate is untextured and the buffer layer is biaxially textured and joined to the substrate via an interlayer which consists is made of a material that is different than zirconium oxide but is compatible with the latter. This product is in particular produced with ion beam-assisted deposition of the buffer layer. It is suitable in particular as a support for a functional layer of a ceramic superconductor, e.g. for use as a superconducting current limiter.
