| Popis: | The accomplishment of high-temperature superconductivity is of immense scientific and technological importance. Several critical transition-temperature barriers have recently been breached since the long-standing record temperature of 23.2 K for Nb3Ge was exceeded. The most important milestones were the announcement of T c ≈ 30 K in lanthanum barium copper oxide by Bed-norz and Muller,1 whose work was based upon materials developed by Michel and Raveau,2 and the work of Chu, Wu, and others,3 based upon the replacement of lanthanum by yttrium, which resulted in superconductivity at temperatures of approximately 95 K. |
