Researchers peg magnetism as key driver of high-temperature superconductivity
When it comes to superconductivity, magnetic excitations may top good vibrations. view more (2006-07-06)
Finding superconductors that can take the heat
Superconductors are materials with no electrical resistance that are used to make strong magnets and must be kept extremely cold-otherwise, they lose their superconducting abilities. view more (2005-11-09)
Towards a new test of general relativity?
Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much larger than expected from general relativity and could help physicists to make a significant step towards the long-sought-after quantum theory of... view more...

Helping Out a High-Temperature Superconductor
Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have discovered a way to significantly increase the amount of electric current carried by a high-temperature superconductor, a material that conducts electricity with no resistance. view more (2005-09-15)
New wrinkle in the mystery of high-Tc superconductors
In the twenty years since the discovery of high-temperature (Tc) superconductors, scientists have been trying to understand the mechanism by which electrons pair up and move coherently to carry electrical current with no resistance. view more (2006-03-17)
More evidence for 'stripes' in high-temperature superconductors
An international collaboration including two physicists from the U.S. Department of Energy's Brookhaven National Laboratory has published additional evidence to support the existence of "stripes" in high-temperature (Tc) superconductors. view more (2006-04-27)
New theory explains enhanced superconductivity in nanowires
Superconducting wires are used in magnetic resonance imaging machines, high-speed magnetic-levitation trains, and in sensitive devices that detect variations in the magnetic field of a brain. view more (2006-10-19)
Delft nano-detector very promising for remote cosmic realms
A miniscule but super-sensitive sensor can help solve the mysteries of outer space. Cosmic radiation, which contains the terahertz frequencies that the sensors detect, offers astronomers important new information about the birth of star systems and planets. view more (2007-01-18)
Physicists set 'speed limit' for future superconducting magnet
A research team led by a Northwestern University physicist has identified a high-temperature superconductor — Bi-2212, a compound containing bismuth — as a material that might be suitable for the new wires needed to one day build the most powerful superconducting magnet in the world, a 30 Tesla magnet. view more (2007-02-12)
Complex order parameter in ruthenate superconductors confirmed
Since it was discovered to be superconducting over a decade ago, the pairing symmetry of strontium ruthenium oxide has been widely explored and debated. Now, a team of researchers led by Dale Van Harlingen at the University of Illinois at Urbana-Champaign say the debate is over. view more (2006-11-28)
Superconductivity can induce magnetism
When an electrical current passes through a wire it emanates heat - a principle that's found in toasters and incandescent light bulbs. view more (2008-09-12)
Pitt researchers create new form of matter
Physicists at the University of Pittsburgh have demonstrated a new form of matter that melds the characteristics of lasers with those of the world's best electrical conductors. view more (2007-05-21)
Newly discovered 'superinsulators' promise to transform materials research, electronics design
Superinsulation may sound like a marketing gimmick for a drafty attic or winter coat. But it is actually a newly discovered fundamental state of matter created by scientists at the U.S. Department of Energy's Argonne National Laboratory in collaboration with several European institutions. view more (2008-04-09)
New understanding for superconductivity at high temperatures
An international research team has discovered that a magnetic field can interact with the electrons in a superconductor in ways never before observed. view more (2008-01-14)
Quantum information now readable
Chalmers researchers in Sweden, in an EU project involving colleagues from France, Holland, Germany, Italy and Finland, have shown that outdata from superconductor quantum computers can be read directly, even though the signal consists only of the presence or absence of two electrons, a so-called Cooper pair. How far away are we from a functional... view more... (2002-04-08)
New superconductors present new mysteries, possibilities
Johns Hopkins University researchers and colleagues in China have 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. view more (2008-06-05)
Superfluid-superconductor relationship is detailed
Scientists have studied superconductors and superfluids for decades. Now, researchers at Washington University in St. Louis have drawn the first detailed picture of the way a superfluid influences the behavior of a superconductor. In addition to describing previously unknown superconductor behavior, these calculations could change scientists'... view more... (2008-08-04)
