High-Tc superconductors toward small scale applications

摘要: This chapter discusses the applications of high-Tc superconductors (HTS), where Tc is critical transition temperature between superconductive and nonsuperconductive states. Various techniques for vortex visualization have also been proposed in chapter. HTSs are layered materials therefore anisotropic. anisotropy depends on fact that HTS quasi-2D: CuO planes, with quasi-metallic conduction, separated by quasi-insulating blocking layers give basic contribution to superconductivity. The conductor close metal-insulator so any slight change growing conditions as well extrinsic nanometric perturbation yields insulating zones planes. crystallographic structures held together electrons form ionic or covalent bonds among atoms. property usually considered a bad property, not only unwanted effects these plaques but aspects
