摘要：

The vortex patterns stabilized by the square array of artificial pinning sites with a tunable pinning strength are studied by using a phenomenological approach in the London limit. The transitions between pinned and deformed triangular lattices are analyzed as a function of the amplitude of vortex-pinning site interaction and the length-scale characteristic of this interaction. The critical current and different phases of vortex lattice are studied in presence of external transport current. (C) 2004 Elsevier B.V. All rights reserved.
