摘要:

本文分析了矩形截面片状样品在垂直磁场中,在有限伦敦穿透深度下迈斯纳态的磁感应强度分布。伦敦方程的精确的2D数值解解析地扩展到现实的3D情况。在铌圆柱体和箔以及YBCO和BSCCO单晶上得到的数据与模型符合得很好。结果是特别相关的磁化率,射频和微波谐振器测量的磁穿透深度在高Tc超导体。

英文摘要:

The distribution of magnetic induction in Meissner state with finite London penetration depth is analyzed for platelet samples of rectangular cross-section in a perpendicular magnetic field. The exact 2D numerical solution of the London equation is extended analytically to the realistic 3D case. Data obtained on Nb cylinders and foils as well as single crystals of YBCO and BSCCO are in a good agreement with the model. The results are particularly relevant for magnetic susceptibility, rf and microwave resonator measurements of the magnetic penetration depth in high-Tc superconductors.
