Processing and characterization of Bi-based single crystals and tapes

摘要: Publisher Summary Superconductivity is a phenomenon that includes two properties of the superconducting materials. The main characteristic total loss electrical resistance when superconductor cooled below Tc, which critical transition temperature between superconductive and nonsuperconductive states, but it does not exactly describe essential nature superconductors. chapter discusses structures High-Tc Superconductors (HTS). HTS potentially greatest technology in field power communications. One conditions needed to obtain high-performance electric conductor using bismuth-based (Bi-2212 or Bi-2223) ceramic powder precursor has fulfill certain general characteristics—such as high phase purity low carbon content. Silver-sheathed Bi-2223 composite tapes are briefly discussed chapter. In layered structure, order parameter energy gap maximum copper oxide (CuO2) layers minimum other layers, thereby resulting modulation along c axis. When magnetic applied parallel vortex cores pass through weakly because suppression smallest there.
