A research group of the Departments of Applied Physics and Electromagnetism of the University of Granada(Spain), directed by Professors Jorge Andrés Portí, Alfonso Salinas and Juan Antonio Morente, have taken a...
When an electrical current passes through a wire it emanates heat - a principle that's found in toasters and incandescent light bulbs. Some materials, at low temperatures, violate this law and carry current without a...
A research team at the Ångström Laboratory at Uppsala University will be leading a collaborative project between the EU and India in theoretical materials science. The objective is to find new materials for app...
Physicists at Los Alamos National Laboratory, along with colleagues at institutions in Switzerland and Canada, have observed, for the first time in a single exotic phase, a situation where magnetism and superconductivity...
A rare class of materials, known as multiferroics, holds great promise for future applications, for example as data storage devices or sensors. However, progress has been hampered by the low operation temperatures and high magnetic fields required to control a property of the materials known as electric polarization. A solution to this problem may have been found by researchers from RIKEN's Advanced Science Institute in Wako and from the Japan Science and Technology Agency (JST), who have synthesized a multiferroic material in which electric polarization can be easily controlled by small magnetic fields.
The semiconductor silicon and the ferromagnet iron are the basis for much of mankind's technology, used in everything from computers to electric motors. In this week's issue of the journal Nature (August 21st) an international group of scientists, including academic and industrial researchers from the UK, USA and Lesotho, report that they have combined these elements with a small amount of another common metal, manganese, to create a new material which is neither a magnet nor an ordinary semiconductor.
An experiment carried out at the Physikalisch-Technische Bundesanstalt (PTB) has realized spin torque switching of a nanomagnet as fast as the fundamental speed limit allows. Using this so-called ballistic switching futu...
Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a development that could help form the basis for higher resolution optical imaging, nanocircuits for high-powered computers, and, to the delight of science-fiction and fantasy buffs, cloaking devices that could render objects invisible to the human eye.
Scientists from Los Alamos National Laboratory, the University of California, Irvine, and the University of California, Davis have proposed a new characterization for the bizarre behavior of certain super-cooled materials--many that act as superconductors--which suggests a paradigm shift in the way scientists understand superconductivity.
A research team led by Dr Oleg Gang at the Brookhaven Center for Functional Nanomaterials (CFN) in New York is using the Zetasizer Nano particle characterization system from Malvern Instruments in ground-breaking work that has demonstrated successful DNA-guided formation of ordered 3-D crystalline structures.
