Argonne National Laboratory scientists have discovered that only half the atoms in some iron-based superconductors are magnetic, providing the first conclusive demonstration of the wave-like properties of metallic magnetism. The discovery allows for a clearer understanding of the magnetism in some compounds of iron, the iron arsenides, and how it helps induce superconductivity, the resistance-free […]

Brookhaven National Laboratory physicist Ignace Jarrige, and University of Connecticut professor Jason Hancock have discovered the mechanism that drives the Kondo Effect. The Kondo Effect is a physical phenomenon that explains how magnetic impurities affect the electrical resistance of materials. Of particular interest are materials that become or cease to be magnetic at different temperatures. […]

Physicists led by Dirk Morr, professor of physics at the University of Illinois at Chicago (UIC), and experimentalists led by Seamus J.C. Davis of Cornell University and Brookhaven National Laboratory have identified the ‘quantum glue’ that underlies a promising type of superconductivity – a crucial step towards the creation of energy superhighways that conduct electricity […]

Last year researchers at Los Alamos National Laboratory (LANL) took a gene that is known to form magnetic nanoparticles in magnetotactic bacteria and expressed it in green algae, where a permanent magnet can be used to separate the transformed algae from a solution. That tasks facing algae production for fuels are: keeping algal production over […]

A new magnetic effect was discovered by accident when a UC Berkeley postdoctoral researcher and several students grew graphene on the surface of a platinum crystal.  Graphene is a one atom-thick sheet of carbon atoms arranged in a hexagonal pattern, that looks like chicken wire.  Examination showed when grown on platinum, the carbon atoms do […]
