Secrets behind high temperature superconductors revealed
Scientists from Queen Mary, University of London and the University of Fribourg (Switzerland) have found evidence that magnetism is involved in the mechanism behind high temperature superconductivity. view more (2009-02-23)
New iron-based and copper-oxide high-temperature
In the initial studies of a new class of high-temperature superconductors discovered earlier this year, research at the Commerce Department's National Institute of Standards and Technology (NIST) has revealed that new iron-based superconductors share similar unusual magnetic properties with previously known superconducting copper-oxide materials. view more (2008-05-29)
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)
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)
MIT reveals superconducting surprise
MIT physicists have taken a step toward understanding the puzzling nature of high-temperature superconductors, materials that conduct electricity with no resistance at temperatures well above absolute zero. view more (2008-02-13)
Superconductivity: Which one of these is not like the other?
Superconductivity appears to rely on very different mechanisms in two varieties of iron-based superconductors. view more (2009-07-13)
Strain has major effect on high-temp superconductors
Just a little mechanical strain can cause a large drop in the maximum current carried by high-temperature superconductors, according to novel measurements carried out by the National Institute of Standards and Technology (NIST). view more (2007-02-16)
UBC physicists develop 'impossible' technique to study and develop superconductors
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. view more (2008-06-24)
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)
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)
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)
Superconductors get a boost from pressure
Superconductors can convey more than 150 times more electricity than copper wires because they don't restrict electron movement, the essence of electricity. view more (2008-05-20)
Researcher solve one mystery of high-temperature superconductors
Unlike low-temperature superconductors, which are metals, high-temperature superconductors are insulators in their normal state. This has puzzled scientists, because half of the electron states are empty. view more (2005-11-29)
'Vortex lattices' may help explain material defects
What do you get when you superimpose a rotating pattern of intersecting laser beams on a spinning cloud of ultracold atoms in a thin gas? Pretty pictures, for one thing-but also a new method that could be used to simulate why and how defects arise in superconductors, important materials that are difficult to study directly. view more (2006-12-26)
The quest for a new class of superconductors
Fifty years after the Nobel-prize winning explanation of how superconductors work, a research team from Los Alamos National Laboratory, the University of Edinburgh and Cambridge University are suggesting another mechanism for the still-mysterious phenomenon. view more (2007-12-21)
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)
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)
The Nobel Prize in Physics 2003
The two Russian physisists Alexei Abrikosov, 75, and Vitaly Ginzburg, 87, and the British physicist Anthony Leggett, 65, will receive this year's Nobel Prize in Physics "for pioneering contributions to the theory of superconductors and superfluids". The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for... view more... (2003-10-09)
Argonne scientists prove unconventional superconductivity in new iron arsenide compounds
Scientists at U.S. Department of Energy's Argonne National Laboratory used inelastic neutron scattering to show that superconductivity in a new family of iron arsenide superconductors cannot be explained by conventional theories. view more (2009-01-13)
New advance towards superconductor wires
Researchers at the Universitat Autònoma de Barcelona, the Materials Science Institute of Barcelona (ICMAB-CSIC), and various German and North American institutions have developed a simple method for measuring the maximum current that coated superconductors can carry. The material will, most likely, be used to manufacture the superconductor... view more... (2004-03-22)
