| 简介 |
The disclosed superconductor arrangement (100) comprises an oxide superconducting layer (30) including at least one superconducting region (31) containing barium, copper, and a rare earth element, having a continuous perovskite structure and having a size of 100 nm x 100 nm x 100 nm or more, and a non-superconducting region (32) in contact with the at least one superconducting region, containing praseodymium, barium, copper, and a rare earth element, having a ratio of a number of atoms of the praseodymium to a sum of a number of atoms of the rare earth element and the praseodymium being 20% or more, having a continuous perovskite structure continuous with the continuous perovskite structure of the superconducting region and having a size of 100 nm x 100 nm x 100 nm or more. Manufacturing by a sol-gel process using plural coating solutions is disclosed as well. |
