Abstract


The critical current densities of superconductor having arrays of square holes and lines hole exposed under electric and perpendicular magnetic field are calculated using time dependent Ginzburg-Landau equation (TDGLE). The result shows that the addition of an array of hole and lines hole enhance the critical current density through different pinning mechanism. The enhancement of critical current by an array of hole addition enhances the critical current densities through commensurate effect and produces the critical current peaks at matching magnetic fields while the addition lines hole to superconductor enhances the critical current through a simple pinning but covering a wider magnetic region. The enhancement factors produced by the both holes are discussed.

Keywords: Superconductor, Time dependent Ginzburg-Landau, Two dimensions, Holes, Critical current
