The discovery of high critical temperature superconductivity is one of the most remarkable chapters in modern science. It is a major breakthrough in developing new technologies and compounds in ...

Earlier experiments gauged the strength of a material’s superconductivity by chilling it until it reached the critical temperature where superconductivity began—with warmer temperatures ...

Superconductivity is the weird phenomenon of zero electrical resistance that occurs when some materials are cooled below a critical temperature. The best superconductors have to be cooled with ...

High-temperature superconductors, which operate at higher critical temperatures than conventional superconductors, hold great promise for enhancing these technologies. Nonetheless, the underlying ...

First discovered by Dutch physicist Heike Onnes in the early 20th century, superconductivity is a rare phenomenon observed in metallic materials where its resistance to electrons flow was lost at ...

However, the superconducting critical temperature, the temperature at which superconductivity takes place, is so low that its practical realization is difficult.

The team describe the critical temperature as “extraordinarily low” and say that it explains why it had previously been difficult to observe superconductivity in quasicrystals. Closer inspection of ...

There are claims of synthesis of a room temperature superconductor. However, these claims have not been officially accepted by scientific communities. Currently, the highest transition temperature (Tc ...

This change in critical temperature is yet another crucial sign of superconductivity. Physicists usually demand all three of these signatures before they accept any claim of superconductivity.

That's roughly -25°C, a temperature that can be reached by a good freezer. Unfortunately, its superconductivity is dependent upon pressure and required compressing the sample between two diamonds.

The Washington team has also studied the effect of applied current on the Tc of their sample. “This measurement gives us a critical current estimate that is remarkably high,” explains Hemley. “We have ...
