✦ Synopsis

We have fabricated finite-sized Pb superconducting networks with 10 Γ‚ 10 square (each 6 Γ‚ 6 lm 2 ) holes by using the electron beam lithography and vortex arrangements are visualized by using magneto-optical imaging. We find that the vortex penetration at low temperature is controlled by defects in the network. We also find nearly regular arrangements of vortices with defects close to 1/2 and1/3 of the matching field.

Vortex behavior of superconducting finite-sized networks with 2 β€’ 2 and 10 β€’ 10 hole arrays has been investigated in a weak magnetic field. Photoresist films spin-coated on silicon substrates were first processed to draw network patterns by using the electron beam lithography. Then, the Pb networks

We present the results of experiments on visualization of magnetic flux distribution and its dynamics in high-temperature superconductors with artificial defects. High-T c superconductor thin films were equipped with a special arrangement of antidots in order to separate the streams of magnetic flux
