Abstract:
A method for making a superconducting oxide precursor film, said method comprising:a) providing an electrodeposition bath comprising an electrolyte medium and a substrate electrode;b) forming an electrolyte solution by providing to the bath soluble metal salts of a plurality of respective metals, oxides of which metals are capable of exhibiting superconductor properties;c) electrodepositing ions of each of the respective metals onto the substrate electrode to form a first electrodeposited layer thereon comprising a mixture of the respective metals in proportions sufficient to be oxidized into a superconducting oxide film;d) removing said substrate electrode having said first electrodeposited layer thereon from said electrolyte solution;e) depositing a layer of silver onto said first electrodeposited layer;f) immersing said substrate electrode having said first electrolyte layer deposited thereon and said silver layer deposited onto said first electrodeposited layer into said electrodeposition solution; andg) electrodepositing ions of each of the respective metals onto the silver layer to form a second electrodeposited layer thereon comprising a mixture of the respective metals in proportions sufficient to be oxidized into a superconducting oxide film to form said superconducting oxide precursor film.
