摘要
Superconducting finite-sized Pb square networks with 10x10 square holes fabricated by electron beam lithography have been investigated in view of vortex doping into superconducting networks. Vortex images observed by a SQUID microscope were compared with predictions from the Ginzburg-Landau theory. Exactly reversed pattern was confirmed to appear both in the vortex-doping x into an empty network and in the antivortex doping 1-x into a fully occupied network (x=1/4). We also confirmed a checker-board crystal of vortices at half filling both theoretically and experimentally.
