Japanese researchers have been immersing iron-based compounds in hot alcoholic beverages such as red wine, sake and shochu to induce superconductivity. Scientists from the National Institute for Materials Science, Japan, found that immersing pellets of an iron-based compound in heated alcoholic beverages for 24 hours greatly increase their superconducting ability. Iron-based compounds usually become superconductive after being exposed to air. This process however can take up to several...

Black holes are some of the heaviest objects in the universe. Electrons are some of the lightest. Now physicists at the University of Illinois at Urbana-Champaign have shown how charged black holes can be used to model the behavior of interacting electrons in unconventional superconductors. "The context of this problem is high-temperature superconductivity," said Phillips. "One of the great unsolved problems in physics is the origin of superconductivity (a conducting state with zero...

Technique suggests an avenue for creating new kinds of superconductivity Physicists at the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland-College Park, have for the first time caused a gas of atoms to exhibit an important quantum phenomenon known as spin-orbit coupling. Their technique opens new possibilities for studying and better understanding fundamental physics and has potential applications to...

A researcher at the National Institute of Standards and Technology (NIST) has invented a method of making high-temperature superconducting (HTS) cables that are thinner and more flexible than demonstration HTS cables now installed in the electric power grid while carrying the same or more current. The compact cables could be used in the electric grid as well as scientific and medical equipment and may enable HTS power transmission for military applications. Described in a paper just published...

Illinois researchers have documented the first observations of some unusual physics when two prominent electric materials are connected: superconductors and graphene. Led by University of Illinois physics professor Nadya Mason, the group published its findings in the journal Nature Physics. When a current is applied to a normal conductor, such as metal or graphene, it flows through the material as a stream of single electrons.  By contrast, electrons travel in pairs in superconductors....

Chemical compounds called manganites have been studied for many years since the discovery of colossal magnetoresistance, a property that promises important applications in the fields of magnetic sensors, magnetic random access memories and spintronic devices. However, understanding"”and ultimately controlling"”this effect remains a challenge, because much about manganite physics is still not known. A research team lead by Maria Baldini from Stanford University and Carnegie...

A team of physicists has taken a big step toward the development of useful graphene spintronic devices. The physicists, from the City University of Hong Kong and the University of Science and Technology of China, present their findings in the American Institute of Physics' Applied Physics Letters. Graphene, a two-dimensional crystalline form of carbon, is being touted as a sort of "Holy Grail" of materials. It boasts properties such as a breaking strength 200 times greater than steel and, of...

Material could be evidence of a new phase of matter debated by physicists; properties could be harnessed for future superconductors, computer electronics In 2008, an international team of scientists studying an exotic new superconductor based on the element ytterbium reported that it displays unusual properties that could change how scientists understand and create materials for superconductors and the electronics used in computing and data storage. But a key characteristic that explains the...
