By combining two frontier technologies, spintronics and straintronics, a team of researchers from Virginia Commonwealth University has devised perhaps the world's most miserly integrated circuit. Their proposed design runs on so little energy that batteries are not even necessary; it could run merely by tapping the ambient energy from the environment. Rather than the traditional charge-based electronic switches that encode the basic 0s and 1s of computer lingo, spintronics harnesses the...

Researchers find magnetic skyrmions in atomically thin metal film Physicists at Hamburg and Kiel University and the Forschungszentrum Jlich have found for the first time a regular lattice of magnetic skyrmions "“ cycloidal vortex spin structures of exceptional stability "“ on a surface. This fascinating magnetic structure was discovered experimentally at the University of Hamburg by spin-polarized scanning tunnelling microscopy and imaged on the atomic scale. Theoreticians at the...

Physicists from Juelich, Kiel and Hamburg identify an atomic-scale magnetic lattice of cycloidal vortices in a thin metal film Physicists at Forschungszentrum Jlich and the universities of Kiel and Hamburg are the first to discover a regular lattice of stable magnetic skyrmions "“ radial spiral structures made up of atomic-scale spins "“ on a surface instead of in bulk materials. Such tiny formations could one day form the basis of a new generation of smaller and more efficient...

A violation of one of the oldest empirical laws of physics has been observed by scientists at the University of Bristol. Their experiments on purple bronze, a metal with unique one-dimensional electronic properties, indicate that it breaks the Wiedemann-Franz Law. This historic discovery is described in a paper published today in Nature Communications.In 1853, two German physicists, Gustav Wiedemann and Rudolf Franz, studied the thermal conductivity (a measure of a system's ability to...

Research reveals vital insight into spintronics Scientists have taken one step closer to the next generation of computers. Research from the Cavendish Laboratory, the University of Cambridge's Department of Physics, provides new insight into spintronics, which has been hailed as the successor to the transistor. Spintronics, which exploits the electron's tiny magnetic moment, or 'spin', could radically change computing due to its potential of high-speed, high-density and low-power consumption....

At the smallest scales, magnetism may not work quite the way scientists expected, according to a recent paper in Physical Review Letters by Rafal Oszwaldowski and Igor Zutic of the University at Buffalo and Andre Petukhov of the South Dakota School of Mines and Technology. The three physicists have proposed that it would be possible to create a quantum dot -- a kind of nanoparticle -- that is magnetic under surprising circumstances. Magnetism is determined by a property all electrons possess:...

Physicists working at the University of California, Santa Barbara and the University of Konstanz in Germany have developed a breakthrough in the use of diamond in quantum physics, marking an important step toward quantum computing. The results are reported in this week's online edition of Nature Physics. The physicists were able to coax the fragile quantum information contained within a single electron in diamond to move into an adjacent single nitrogen nucleus, and then back again using...

Physicists at the University of Arizona have achieved a breakthrough toward the development of a new breed of computing devices that can process data using less power In a recent publication in Physical Review Letters, physicists at the University of Arizona propose a way to translate the elusive magnetic spin of electrons into easily measurable electric signals. The finding is a key step in the development of computing based on spintronics, which doesn't rely on electron charge to digitize...

A gyroscope uses the principles of conservation and angular momentum to measure and maintain orientation. The mechanical gyroscope is a spinning wheel or disk whose axle is free to take any orientation. The gyroscope's high rate of spin allows for large angular momentum which makes the orientation changes much more responsive to a given external torque. There is also the electronic, microchip-packaged MEMS gyroscope, solid state ring laser and fiber optic gyroscope, as well as the extremely...
