Abstract
Provided is a superconducting wire. The superconducting wire comprises a substrate, a superconducting film on the substrate and a pinning center in the superconducting film. The superconducting film includes Y1-xRExBCO and the pinning center has an additive of Ba2YNbO6.
Claims11
A method of forming a superconducting wire, comprising:
- forming a buffer layer on a substrate;
- and
- providing a superconducting precursor on the buffer layer, to form a superconducting film including Y1-xRExBCO on the substrate,
- wherein:
- 0<x≤1,
- the superconducting film has a first composition ratio of Y+RE and Cu relative to Ba,
- the superconducting precursor is provided using a source including Y+RE, Ba, and Cu,
- the source has a second composition ratio of Y+RE and Cu relative to Ba, and
- the second composition ratio is greater than the first composition ratio.
