摘要：
The initial magnetization curve of square-columnar Josephson-junction arrays is calculated From fundamental laws. It is found that the first vortex entry is controlled by vortex nucleation rather than surface depinning and it occurs at a field greater than that predicted by the traditional surface-barrier theory.
