Room-temp superconductors could be possible

Superconductors are the holy grail of energy efficiency. These mind-boggling materials allow electric current to flow freely without resistance. But that generally only happens at temperatures within a few degrees of absolute ...

Melting of frozen electrons visualized

For the first time, physicists have visualized the 'melting' of electrons inside a special class of insulators that allows electrons to move freely; the process turns the insulator into a metal and possibly later into a superconductor. ...

New material could advance superconductivity

Scientists have looked for different ways to force hydrogen into a metallic state for decades. A metallic state of hydrogen is a holy grail for materials science because it could be used for superconductors, materials that ...

New ferromagnetic superconductor—CsEuFe4As4

Superconductivity (SC) and ferromagnetism (FM) are mutually antagonistic collective phenomena in solids. Macroscopically, a superconductor expels magnetic fluxes from its interior below the superconducting critical temperature ...

Quantum filter has 20,000 Josephson junctions

(—A team of researchers at CSIRO Manufacturing, in Australia has created several test quantum filters with arrays having as many as 20,000 Josephson junctions. In their paper published in Superconductor Science ...

Physicists discover flaws in superconductor theory

University of Houston physicists report finding major theoretical flaws in the generally accepted understanding of how a superconductor traps and holds a magnetic field. More than 50 years ago, C.P. Bean, a scientist at General ...

Superconductivity seen in a new light

Superconducting materials have the characteristic of letting an electric current flow without resistance. The study of superconductors with a high critical temperature discovered in the 1980s remains a very attractive research ...

A quantum leap for the next generation of superconductors

Quantum materials – materials designed at the sub-atomic level – can be finely-tuned to achieve extremely useful properties that are often not found in nature. These include superconductivity, the ability to conduct electricity ...

Physicists discover new properties of superconductivity

New findings from an international collaboration led by Canadian scientists may eventually lead to a theory of how superconductivity initiates at the atomic level, a key step in understanding how to harness the potential ...
