... sample supplied by materials scientists in Beijing, they revealed a magnetism that is similar to that found in copper-oxide superconductors, that is, layers of magnetic moments—like many individual ...
... scientists discovered a class of what they call high-temperature superconductors made of ceramic copper oxides, called cuprates. They found that at temperatures as high as about 135 K, or -216º F, ...
... Damascelli, the team deposited potassium atoms onto the surface of a piece of superconducting copper oxide. The approach allows the scientists to continuously manipulate the number of electrons on ...

Scientists have been unable to decipher just how copper-oxide HTS materials become superconductors. ... natural state, copper-oxide behaves like a permanent magnet. Scientists "dope" the material ...

NIST researcher Mark Kedzierski has found that dispersing “sufficient” amounts of copper oxide particles (30 nanometers in diameter) in a common polyester lubricant and ...
... been a mystery, until now.
To search for pre-formed electron pairs, the Brookhaven team bombarded a copper-oxide material, held at temperatures above and below the transition ...
... superconductors. In addition to being easier to shape into wires and otherwise commercialize than today's copper-oxides, such materials provide scientists fresh new subjects with which to develop and ...
... that point.
But earlier Brookhaven studies suggest that the stripes do exist in other, superconducting copper oxides, in a way that is more fluid and therefore harder to detect. [see: [http://www. ...
... that the superconductivity has an unconventional mechanism, perhaps like high temperature copper oxide superconductors. Some iron arsenides are antiferromagnetic, rather than superconducting, so ...
... a ceramic high-temperature superconductor known as Bi 2201, a copper oxide, documented that the pseudogap doesn't just precede superconductivity. It continues to co-exist once the material ...
