The Phenomenon: Occurrence and Characteristics -- Crystal structure of High Temperature Superconductors -- Critical Current -- Synthesis of High Superconductors -- Superconductivity in Cuprates -- The Proximity and Josephson Effects -- Theories of superconductivity -- Application of superconductivity.

The present book aims at describing the phenomenon of superconductivity and high-temperature superconductors discovered by Bednorz and Muller in 1986. The book covers the superconductivity phenomenon, structure of high-Tc superconductors, critical currents, synthesis routes for high Tc materials, superconductivity in cuprates, the proximity effect and SQUIDs, theories of superconductivity and applications of superconductors.
