SUPERCONDUCTING MATERIALS – A TOPICAL OVERVIEW Roland Hott1, Reinhold Kleiner2, the expulsion of magnetic fields from a superconductor, discovered in , shows that Nevertheless, in spite of earlier concerns about the ceramic nature of HTS. High-temperature superconductors (abbreviated high-T c or HTS) are materials that behave as superconductors at unusually high temperatures. The first high-T c superconductor was discovered in by IBM researchers Georg Bednorz and K. Alex Müller, who were awarded the Nobel Prize in Physics "for their important break-through in the discovery of superconductivity in ceramic materials". YBa 2 Cu 3 O 7−x was the first ceramic superconductor discovered with T c greater than liquid nitrogen temperature. Texturing is essential to achieve high current densities in polycrystalline wires or the thick films of ceramic superconductors. The high-T c field is continually expanding. The most significant new materials are bismuth-based.

Superconductivity, Ceramic superconductors, Infrared detectors, predict that room-temperature superconducting materials, if possible at all, may require.SUPERCONDUCTING MATERIALS – A TOPICAL OVERVIEW Roland Hott1, Reinhold Kleiner2, the expulsion of magnetic fields from a superconductor, discovered in , shows that Nevertheless, in spite of earlier concerns about the ceramic nature of HTS. C.-L. Yeh, in Reference Module in Materials Science and Materials Engineering, Combustion Synthesis of Complex Oxides. Another research avenue for the SHS process involving the gasless and permeation stages is related to the synthesis of high-temperature ceramic superconductors, which are complex cuprates based on yttrium, bismuth, and thallium.

ELECTRICAL ENGINEERING – Vol. II - Superconducting Materials and Devices - C.P. Foley ©Encyclopedia of Life Support Systems (EOLSS) An important magnetic characteristic of a bulk superconductor is its thermodynamic critical field, Hc. In normal materials, magnetic fields penetrate with only a small attenuation. The ceramic materials used to make superconductors are a class of materials called perovskites. The superconductor we will be experimenting with is an yttrium (Y), barium (Ba) and copper (Cu) composition. Chemical formula is YBa2Cu3O7. This superconductor has a critical transition temperature around 90K, well above liquid nitrogen's 77K.
