摘要
我们回顾了 Delrieu 从 Gorkov 方程推导出的 Bardeen-Cooper-Schrieffer (BCS) 第二类超导体在其 Bc2 相边界附近（即磁化强度很小时）的磁形状因子。随后进行了形状因子、场图和场分布的数值研究。研究了从低温 BCS 到高温 Ginzburg-Landau 涡旋晶格转变的特征。讨论了低温下以及作为外场强度函数的分量场分布和形状因子的奇异形状。我们的数值工作应有助于分析为 BCS 超导体以及可能其他清洁极限下的超导体记录的小角中子散射和 μ 子自旋旋转涡旋晶格数据。

备注
A mistake for the form factor normalization was made in our original draft. In this version Eqs.: (25), (31), (32), (35), (D5), (D6), and (E4) are corrected by including the missing factor 1/4\pi. Second sentence of Sec. VII referring to Eq. (E4) was also corrected
