摘要: The superconductor structure has a metallic, biaxially textured mount, an intermediate layer system deposited on the mount and including at least two intermediate layers composed of different oxidic materials and, on this, a high-Tc superconducting layer of the M2Cu3Ox type (RE=rare earth; M=alkaline-earth metal). The intermediate layer which faces the mount is composed of Y2O3, and the relatively thinner intermediate layer which faces the superconducting layer is composed of CeO2. The layers are preferably grown heteroepitaxially.
