OXIDE SUPERCONDUCTING THIN FILM

摘要

PROBLEM TO BE SOLVED: To provide an oxide superconducting thin film with which an oxide superconducting material has a higher critical current, more specifically exhibiting improved critical current characteristics.

SOLUTION: An oxide superconducting thin film includes a substrate and a superconducting layer containing: an oxide superconductor formed on one principal plane of the substrate and oriented along the c-axis in the vertical direction relative to the one principal plane; and a different phase particle having crystal orientation different from that of the oxide superconductor and having an average particle size of 100 nm or more and 500 nm or less. The different phase particle includes a Cu-O particle. The "Cu-O" particle is a particle including at least one of CuO and Cu2O.
