Compounds called nickelates can conduct electricity without resistance well above absolute zero and at ambient pressure.

A team of engineers and physicists at Southern University of Science and Technology, in China, has created a nickel-based material that behaves as a superconductor above the -233°C (40 K) threshold ...

"Our study theoretically predicted topological s-wave superconductivity in superconductor materials that include iron-based superconductors," explains Kobayashi. "We revealed a rich topological ...

The good news is that promising candidates have begun to appear, like iron-based superconductors discovered in 2008. It is becoming increasingly clear that high-temperature superconductivity might ...

Exotic superconducting states can exist in common iron-based superconductors, according to a theoretical analysis Figure 1: A diagram showing one case of the energy dispersion of surface states in an ...

The discovery of a new class of high-temperature superconductors based on iron tests the limits of current theoretical and computational tools for the understanding of strongly correlated systems.
