论文摘要
我们在狭窄的薄膜超导条中研究涡流电流分布。如果一个人将涡流核心定义为曲线，当前电流达到衰减价值，出现了有趣的特征。我们基于伦敦方法的结论只有自然的相关性，因为该方法在核心附近分解了。仍然有用的主要观察结果可能是在附近的核心尺寸在附近的核心尺寸，而不是限制的。此外，边缘。
We study vortex current distributions in narrow thin-film superconducting strips. If one defines the vortex core ``boundary" as a curve where the current reaches the depairing value, intriguing features emerge. Our conclusions based on the London approach have only qualitative relevance since the approach breaks down near the core. Still, the main observation which might be useful is that the core size near the strip edges is smaller than in the rest of the strip. If so, the Bardeen-Stephen flux-flow resistivity should be reduced near the edges. Moreover, at elevated temperatures, when the depairing current is small, the vortex core may extend to the whole strip width, thus turning into an edge-to-edge phase-slip line.
