Kamran, M. Anis-ur-Rehman, Khalid Mansoor, S. He, X. Qiu] Patterned superconducting thin films having a periodic array of submicrometric pinning centers have been of great interest due to their excellence for the studies of the vortex pinning mechanisms in the type-II superconductors. Square hole array has been fabricated over a micro-bridge 60 mm×60 mm of NbN thin film by electron beam lithography. Previous works have been carried out in Nb, Pb and Al thin films where the vortex pinning effect is assumed to be small. In this work, we study the matching pinning effect by the artificial hole array in superconducting NbN thin films. We observed the interplay between the vortex quantization and the artificial hole array. Magneto-resistance minima at integer matching fields up to five times of H 1 (the first matching field corresponding to one vortex inside each hole) and fractional matching fields at 1/2H 1, 3/2H 1 and 5/2H 1 have been observed.
