Dagotto: Correlated electrons in high-temperature superconductors the fiel of high T„like SQUID (superconducting quan- tum interference device) magnetometers and Josephson integrated circuits (Simon, ),although exciting, early promises of levitating trains seem unlikely. The critical current densities are still not high enough for most tech- nological applications, but progress is File Size: 3MB. The high temperature superconductors refer to all the materials that are made up of compounds or elements which are superconducting and transition temperatures but above 30k or c. Between the year and , the transitional temperature was believed to be 30k.
