Özet
The vortex states interacting with a triangular lattice of pinning sites in a two-dimensional (2D) superconducting sample have been investigated by using a molecular dynamics approach. The Nordborg-Vinokur potential is used to model the interaction between the vortices and the pinning sites. We have found several ordered vortex configurations, such as pentagons, hexagons, and shells depending on two critical parameters of the system, namely pinning radius and vorticity. Our results are in good agreement with the results of Bitter decoration experiments performed on type-II superconductors with blind hole and pillar arrays. (C) 2009 Elsevier B.V. All rights reserved.
