What has the author Emanuel Kaldis written?
Emanuel Kaldis has written: 'High-Tc superconductivity 1996' -- subject(s): Congresses, High temperature superconductivity, Copper oxide superconductors
Why was the discovery of high-temperature superconductors so startling to scientists?
It was startling because it was said to be impossible by the BCS theory.
Lowest temperature of superconductivity?
The lowest temperature at which superconductivity can occur is called the critical temperature. This temperature varies depending on the material. Some superconductors have critical temperatures close to absolute zero (0 Kelvin), while others have critical temperatures as high as -140 degrees Celsius.
Can you name some superconductors having high critical temperature?
some superconductors having high critical temperature :YBa2Cu3O7 have Tc=93 K (1987)BiSr2CaCu2O8+x Tc=94 K (1988)Ta2Ba2Ca2Cu3O10+x Tc=125 K (1988)HGBa2Ca2Cu3O8+x Tc=150 K (1993)
What are most modern high temperature superconductors made of?
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.

Anderson has written: 'Basic notions of condensed matter physics' -- subject(s): Many-body problem, Perturbation (Quantum dynamics), Condensed matter 'The theory of superconductivity in the high-Tc cuprates' -- subject(s): Congresses, High temperature superconductors, Copper oxide superconductors
What is the pairing mechanism behind high-temperature superconductivity?
The pairing mechanism behind high-temperature superconductivity is the ability of certain materials to conduct electricity with zero electrical resistance.
Why was the discovery of high temperature superconductors so startling to scientist?
The discovery of high temperature superconductors was startling to scientists because it defied previous understanding of superconductivity, which was thought to only occur at very low temperatures. These new materials exhibited superconducting properties at relatively higher temperatures, opening up new possibilities for practical applications.
What has the author Yeoh Lee Moi written?
Yeoh Lee Moi has written: 'Phase formation and superconductivity in copper oxide based YBCO and RU-1212 and RU-1222 systems prepared by sol-gel and coprecipitation techniques' -- subject(s): Ruthenium compounds, High temperature superconductors, Copper oxide superconductors, Yttrium alloys, Phase rule and equilibrium
What is the definition of low temperature supercoductors?
In a way, all currently existing superconductors are "low-temperature", but some more so than others. The traditional superconductors work up to about 20 K (or minus 253 Centigrade); more recent "high-temperature superconductors" work up to 100 K or so. 100 K is still minus 173 Centigrade, but it is much "hotter" than the traditional superconductors. The new "high-temperature" superconductors apparently work different than the old-fashioned ones; at least, the theory that explains the traditional superconductors fails to explain how the new superconductors work.
What superconductor works best with higher temperature?
High-temperature superconductors are most commonly based on copper-oxide or iron-based compounds. Among these, yttrium barium copper oxide (YBCO) is one of the most widely studied and used high-temperature superconductors due to its relatively high critical temperature of around 90 K.
