Title:
SUPERCONDUCTOR, AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/241282
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a superconductor having a high critical current density and a sufficiently low surface resistance. To achieve the objective, the superconductor comprises: a substrate; a superconducting layer including a ReBa2Cu3Ox-based compound arranged on the substrate (Re represents at least one element selected from the group consisting of Y, Nd, Sm, Gd, Dy, Eu, Er, Yb, Pr, and Ho, and x represents 6.2-7.0). The surface resistance of the superconducting layer is at most 1 kΩ, and the critical current density of the superconducting layer in a self-magnetic field at 77 K is at most 3.0 MA/cm2.
