Effect of Coherence Length in the C-Axis on Irreversibility Properties in Anisotropic High Temperature Superconductors

摘要: Effect of coherence length on the irreversibility line is discussed based collective flux creep theory for anisotropic high temperature superconductors. The case pinning by isotropic nonsuperconducting particles treated. It shown that bundle size smaller resulting in poorer properties superconductors with shorter c-axis field normal to c-axis. When applied along c-axis, it expected limited become large probably due defects fluxoid lattice. This effect and small upper critical limit line. concluded quasitwo-dimensional are inferior three-dimensional ones respect properties.
