NIST discovers how strain at grain boundaries suppresses high-temperature superconductivity
Researchers at the National Institute of Standards and Technology (NIST) have discovered that a reduction in mechanical strain at the boundaries of crystal grains can significantly improve the performance of high-temperature superconductors (HTS). view more (2009-06-18)
Magnetism governs properties of iron-based superconductors
Though a year has passed since the discovery of a new family of high-temperature superconductors, a viable explanation for the iron-based materials' unusual properties remains elusive. But a team of scientists working at the National Institute of Standards and Technology (NIST) may be close to the answer. view more (2009-03-26)
Iron-arsenic superconductors in class of their own
Physicists at the U.S. Department of Energy's Ames Laboratory have experimentally demonstrated that the superconductivity mechanism in the recently-discovered iron-arsenide superconductors is unique compared to all other known classes of superconductors. view more (2009-04-30)
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)
New particle explains odd behavior in cuprate superconductors
New fundamental particles aren't found only at Fermilab and at other particle accelerators. They also can be found hiding in plain pieces of ceramic, scientists at the University of Illinois report. view more (2007-07-18)
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...

Exotic Materials Using Neptunium, Plutonium Provide Insight into Superconductivity
Physicists at Rutgers and Columbia universities have gained new insight into the origins of superconductivity - a property of metals where electrical resistance vanishes - by studying exotic chemical compounds that contain neptunium and plutonium. view more (2008-07-22)
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)
Scientists reveal effects of quantum 'traffic jam' in high-temperature superconductors
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory, 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... view more...

Thinnest superconducting metal created
A superconducting sheet of lead only two atoms thick, the thinnest superconducting metal layer ever created, has been developed by physicists at The University of Texas at Austin. view more (2009-06-09)
Powerful superconductor is in a class all its own
Superconductivity has perplexed, astounded and inspired scientists ever since it was discovered in 1911. Now, in the latest of a century of surprises, researchers at the National High Magnetic Field Laboratory at Florida State University have discovered unusual properties in a novel superconducting material that point to an entirely new kind of... view more...

Recent discoveries regarding the physics of ceramic superconductors may help improve scientists' understanding of resistance-free electrical power. view more (2007-05-31)
'Cooper pairs' can be found in insulators as well superconductors
Nearly a century ago, Dutch physicist Kamerlingh Onnes discovered that some metals transform into perfect electrical conductors when cooled to temperatures near absolute zero. Once started, their currents of electrons can flow perpetually. view more (2007-11-26)
The new 'look' of superconductivity
Ames Laboratory physicist Ruslan Prozorov's discovery of the complex patterns in superconducting lead marks a noteworthy departure from the model first proposed by Russian physicist Lev Landau in the 1930s. view more (2007-07-09)
New Instrument Puts New Spin on Superconductors
Researchers at the U.S. Department of Energy's Ames Laboratory are part of collaborative team that's used a brand new instrument at the DOE's Spallation Neutron Source to probe iron-arsenic compounds, the "hottest" new find in the race to explain and develop superconducting materials. view more (2008-10-13)
High-temperature superconductors: magnetic glue may be the clue
Striking pictures of magnetic waves inside advanced ceramics may be the clue to understanding how they can transmit electricity without losing energy, according to results obtained by two teams of scientists using the UK's world-leading ISIS neutron source in Oxfordshire and published this week in the journal Nature. The ceramics, known as... view more... (2004-06-02)
UAB Researchers Develop a Model for Optimising the Magnetic Levitation of Superconductors
A research team in the Physics Department at the UAB, formed by Àlvar S' nchez, Carles Navau (also lecturer and researcher at the Escola Universitaria Salesiana de Sarri' ) and Enric Pardo, have developed a complete theoretical model that allows for the detailed study of the magnetic force of levitation that appears in a high-temperature... view more...
