Iowa State part of materials science collaboration highlighted during meeting An Iowa State theoretical physicist will describe the latest ideas in high-temperature superconductivity during the annual meeting of the American Association for the Advancement of Science Feb. 17-21 in Washington, D.C. Jörg Schmalian, an Iowa State professor of physics and astronomy and an associate of the U.S. Department of Energy's Ames Laboratory, will be part of a symposium addressing the 100-year history...

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....

Measurements on super-short timescale indicate loss of coherence among electron pairs and may help explain the mechanism of high-temperature superconductivity As part of an ongoing effort to uncover details of how high-temperature superconductors carry electrical current with no resistance, scientists at Johns Hopkins University and the U.S. Department of Energy's Brookhaven National Laboratory have measured fluctuations in superconductivity across a wide range of temperatures using terahertz...

Neutron scattering analysis of two families of iron-based materials suggests that the magnetic interactions thought responsible for high-temperature superconductivity may lie "two doors down": The key magnetic exchange pairings occur in a next-nearest-neighbor ordering of atoms, rather than adjacent atoms. Researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, using the Spallation Neutron Source's ARCS Wide Angular Range Chopper Spectrometer,...

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...

A new fractional vortex state observed in an unconventional superconductor may offer the first glimpse of an exotic state of matter predicted theoretically for more than 30 years. In a paper published in the January 14 issue of Science, University of Illinois physicists, led by Raffi Budakian, describe their observations of a new fractional vortex state in strontium ruthenium oxide (SRO). Such states may provide the basis for a novel form of quantum computing in which quantum information is...

US-European team revisits 30-year-old breakthrough with new methods, understanding European and U.S. physicists this week are offering up the strongest evidence yet that magnetism is the driving force behind unconventional superconductivity. The findings by researchers from Rice University, the Max Planck Institute for Chemical Physics of Solids (MPI-CPfS) in Dresden, Germany, and other institutions were published online today in Nature Physics. The findings follow more than three decades of...

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
