| Outline of Final Research Achievements |
We tried to develop high-throughput optimization technique in superconductors with asymmetric flux pinning centers aiming to high efficient superconducting power applications. We fabricated Nd superconducting thin films with nano-seized circles (NCSs), which act as flux pinning centers (PCs). These NSCs contributed to an enhancement of critical current density (Jc) in the Nb films, and Jc increased with increasing number density of the NCSs. We simulated dynamics of flux quantum (FQ) in two-dimensional space. A superconductor model with sawtooth shape in the one side exhibited an asymmetric current-voltage curve.
