high temperature superconductors

(National Institute of Standards and Technology (NIST)) Researchers at NIST are decoding the mysterious mechanisms behind the high-temperature superconductors that industry hopes will find wide use in next-generation systems for storing, distributing and using electricity.

Like astronomers tweaking images to gain a more detailed glimpse of distant stars, Brookhaven physicists have found ways to sharpen images of the energy spectra in high-temperature superconductors — materials that carry electrical current effortlessly when cooled below a certain temperature.

These new imaging methods confirm that the electron pairs needed to carry current emerge above the transition temperature, before superconductivity sets in, but only in a particular direction.

(DOE/Brookhaven National Laboratory) Like astronomers tweaking images to gain a more detailed glimpse of distant stars, physicists at the US Department of Energy's Brookhaven National Laboratory have found ways to sharpen images of the energy spectra in high-temperature superconductors -- materials that carry electrical current effortlessly when cooled below a certain temperature.

These new imaging methods confirm that the electron pairs needed to carry current emerge above the transition temperature, before superconductivity sets in.

Scientists at Brookhaven National Laboratory and collaborators have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors cannot simply be elevated by increasing the electrons' binding energy.

Scientists at Brookhaven Lab, in collaboration with colleagues at Cornell University, Tokyo University, the University of California, Berkeley, and the University of Colorado, have uncovered the first experimental evidence for why the transition temperature of high-temperature superconductors — the temperature at which these materials carry electrical current with no resistance — cannot simply be elevated by increasing the electrons’ binding energy.

(National High Magnetic Field Laboratory) Using very high magnetic fields, scientists observe the underlying structure of mysterious copper-oxide high-temperature superconductors.

Researchers have developed a technique that controls the number of electrons on the surface of high-temperature superconductors, a procedure considered impossible for the past two decades.

(University of British Columbia) A team of University of British Columbia researchers has developed a technique that controls the number of electrons on the surface of high-temperature superconductors, a procedure considered impossible for the past two decades.

(Johns Hopkins University) Researchers gave unlocked some of the secrets of newly discovered iron-based high-temperature superconductors, research that could result in the design of better superconductors for use in industry, medicine, transportation and energy generation.

In the initial studies of a new class of high-temperature superconductors discovered earlier this year, research has revealed that new iron-based superconductors share similar unusual magnetic properties with previously known superconducting copper-oxide materials.
