Vortex-lattice pinning and critical current density in anisotropic high-temperature superconductors

摘要: The anisotropy of critical current density is an impressive manifestation in the physics high-temperature superconductors. We develop analytical characterization anisotropic flux-lattice pinning and a system random point defects. effect superconducting on force formulated. in-plane/out-of-plane microscopic characteristic lengths are incorporated field angular dependence density. This helpful understanding physical essence scaling behavior experiments for anisotropy. discuss role strong weak defects pinning. Relevance theory to critical-state model dictated as well.
