Abstract

The new critical-current-bydesign paradigm was demonstrated on technologically important rare earth barium copper oxide coated conductors. The time-dependent Ginzburg-Landau (TDGL) simulations elucidate the vortex dynamics responsible for the non-additive behavior of the vortex-defect interaction in the presence of different types of correlated defects with various spatial orientations. In particular, a vortex-sliding scenario was also observed, directly demonstrating the dynamics that can result from synergies between different types of pinning. Using this approach, we also can predict the optimal concentrations of these defects for maximal critical current.
