Crystallization Mechanisms of High Critical Temperature Superconductors

摘要: The crystal growth mechanisms of high critical temperature ( T c ) superconducting (HTSC) materials with experimental results single crystals and polycrystalline bulk highly oriented grains are reviewed, especially focusing on YBa 2 Cu 3 O 7-δ REBa , the most widely studied HTSC material. By first considering basic fundamental solidification processes oxides, physical models process a unique idea peritectic reaction rate-limiting stages diffusion in liquid as well interface kinetics for faceted have been reviewed. model based series particle pushing/trapping mechanism controlling microstructures understanding behavior stable solid phase has also Finally, pulling fabrication crystals, developed ternary component system, discussed well.
