摘要：
We study flux penetration in a disordered type II superconductor by simulations of interacting vortices, using a Monte-Carlo method for vortex nucleation. Our results show that a detailed description of the nucleation process yields a correction to the scaling laws usually associated with flux front invasion. We propose a simple model to account for these corrections. (C) 2004 Elsevier B.V. All rights reserved.
