Influence of Inhomogeneous Superconducting Properties of YBCO Thin Film on Current Limiting Characteristics

This paper describes numerical analysis of current limiting characteristics of YBCO thin film with inhomogeneous superconducting properties. The analysis tool uses a finite element method (FEM) based on current vector potentials. First, the validity of the analysis tool was verified by comparing with experimental results using small samples. Then we analyzed large-size meander-shaped thin films and discussed the influence of inhomogeneous superconducting properties of YBCO thin film on current limiting characteristics.
