Abstract
We perform computer simulations for vortex dynamics in high-Tc dot arrays embedded in conventional low Tc superconductors by solving numerically the time-dependent Ginzburg-Landau (TDGL) equation. The high-T c dot repels vortices, which is in contrast to the anti-dot which works as a strong attractive pinning center. We find that vortex dynamics in the system is much different from that of the anti-dot array systems. For example, vortices can widely distribute outside the dot region when the applied magnetic field H is less than Hc2 of the substrate superconductor (H sc2), while vortices are confined inside very narrow regions between neighboring dots when H>Hsc2. The complex dynamics is explained in terms of the change of interaction between vortices at Hsc2.
