Abstract
A method for producing a superconducting layer of YBa.sub.2 CU.sub.3 O.sub.7 on a sapphire substrate utilizes the steps of epitaxially growing an intermediate layer that at least contains a yttrium-stabilized zirconium oxide layer directly on the substrate, and then epitaxially growing a superconducting layer on the intermediate layer. In one embodiment, the step of growing the intermediate layer grows two sub-layers, with the first sub-layer being a yttrium-stabilized zirconium oxide layer and a second sub-layer being a yttrium oxide layer applied onto the first sub-layer.
