First claim
Opening claim text (preview).
The invention claimed is: 1. A superconducting oxide thin film, comprising a superconducting layer formed on a supporting material, the superconducting layer including an RE-based superconductor as a main component, and the RE-based superconductor including a CuO chain having a Cu vacancy portion. 2. The superconducting oxide thin film of claim 1 , wherein the RE-based superconductor includes a CuO single chain as the CuO chain, and the Cu vacancy portion is a linear defect formed by consecutive vacancies of Cu atoms in the CuO single chain. 3. The superconducting oxide thin film of claim 2 , wherein the Cu vacancy portion is a linear defect formed by consecutive vacancies of Cu atoms along a chain direction in the CuO single chain. 4. The superconducting oxide thin film of claim 1 , wherein the RE-based superconductor includes a CuO single chain as the CuO chain, the Cu vacancy portion is formed by consecutive vacancies of Cu atoms in the CuO single chain along a b-axis direction of a crystal structure of the RE-based superconductor, and the RE-based superconductor includes a plurality of Cu vacancy portions along an a-axis direction of the crystal structure, and includes Cu atoms at positions between the plurality of Cu vacancy portions arranged in the a-axis direction. 5. The superconducting oxide thin film of claim 1 , wherein the RE-based superconductor includes a CuO double chain as the CuO chain, and the Cu vacancy portion is formed by consecutive vacancies of Cu atoms in a chain direction in at least one CuO chain of two CuO chains in the CuO double chain. 6. The superconducting oxide thin film of claim 1 , wherein the RE-based superconductor includes a CuO single chain and a CuO double chain as the CuO chain, and the Cu vacancy portion is formed by consecutive vacancies of Cu atoms in a chain direction in at least one CuO chain among a plurality of CuO chains configuring the CuO single chain and the CuO double chain. 7. The superconducting oxide thin film of claim 1 , wherein the RE-based superconductor includes a CuO double chain as the CuO chain, and an oxygen atom vacancy is included in one CuO chain among CuO chains configuring the CuO double chain.
