A surprising breakthrough moment in superconducting physics has come from, of all places, a boozy office party at the National Institute for Materials Science in Tsukuba Japan, according to a recent AFP report. Researchers, lead by Yoshihiko Takano, made their discovery when they put tablets of an iron-based compound called Fe(Te,S) into alcoholic drinks at an office party a year ago. The phenomenon of superconductivity is the zero-loss flow of electricity through certain materials. When an...

In a four-decade, Holy Grail-like quest to fully understand what it means to be in a "supersolid" state, physicists have found that supersolid isn't always super solid. In other words, this exotic state of frozen helium appears to have liquid-like properties, says a new paper published in the journal Science (May 13, 2011). Why is this important? Understanding supersolid helium brings us closer to understanding its close cousins superconductivity and superfluidity. Physicists had long thought...

Technique reveals quantum phase transition; could lead to superconducting transistors for power-saving electronics Like atomic-level bricklayers, researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are using a precise atom-by-atom layering technique to fabricate an ultrathin transistor-like field effect device to study the conditions that turn insulating materials into high-temperature superconductors. The technical break-through, which is described in the...

ZURICH, April 18, 2011 /PRNewswire/ -- Twenty-five years ago IBM (NYSE: IBM) scientists, J. Georg Bednorz and K. Alex Muller altered the landscape of physics when they observed superconductivity in an oxide material at a temperature 50 percent higher(1), (-238 deg C, -397 deg F) than what was previously known. This discovery opened an entirely new chapter in the field of physics and earned them the Nobel Prize for Physics in 1987. (Photo:...

Although its name may make many people think of flowers, the element germanium is part of a frequently studied group of elements, called IVa, which could have applications for next-generation computer architecture as well as implications for fundamental condensed matter physics. New research conducted by Xiao-Jia Chen, Viktor Struzhkin, and Ho-Kwang (Dave) Mao from Geophysical Laboratory at Carnegie Institution for Science, along with collaborators from China, reveals details of the element's...

Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this "pseudogap" has been a 20-year quest for researchers who are trying to control and improve these breakthrough materials, with the ultimate goal of finding superconductors that operate at room temperature."Our findings point to management and control of this other phase as the correct path toward...

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...
