Previous world record shattered during 6-experiment pulse Researchers at Los Alamos National Laboratory's biggest magnet facility today met the grand challenge of producing magnetic fields in excess of 100 tesla while conducting six different experiments. The hundred-tesla level is roughly equivalent to 2 million times Earth's magnetic field. "This is our moon shot, we've worked toward this for a decade and a half," said Chuck Mielke, director of the Pulsed Field Facility at Los Alamos....

Scientists manufacture a cylinder which hides contents and makes them invisible to magnetic fields UAB researchers, in collaboration with an experimental group from the Academy of Sciences of Slovakia, have created a cylinder which hides contents and makes them invisible to magnetic fields. The device was built using superconductor and ferromagnetic materials available on the market. The cylinder is built using high temperature superconductor material, easily refrigerated with liquid...

Atoms Caught Moving Within A Molecule

Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule. Key to the experiment, which appears in this week's issue of the journal Nature, is the researchers' use of the energy of a molecule's own electron as a kind of "flash bulb" to illuminate the molecular motion. The team used ultrafast laser pulses to knock one electron out of its natural orbit in a molecule. The electron then fell back toward the molecule scattered off...

Helmholtz-Zentrum Berlin developed a magnetic valve that novel electronic devices can be realistic In close collaboration with colleagues from Bochum and the Netherlands, researchers from the Helmholtz-Zentrum Berlin (HZB) have developed a novel, extremely-thin structure made of various magnetic materials. It is suitable as a kind of magnetic valve for data-storage units of the most recent generation and makes use of effects in the context of so-called spintronics, with which, in addition...

How long does it take an electron to form a photon? The answer would normally be: so short a time that it cannot be measured. However, the international CERN team responsible for experiment NA63 — mainly staffed by physicists from Aarhus University — has now succeeded in dragging out the process, thereby making it measurable. They achieved this by utilizing the phenomena of objects moving slower and shortening in length from Einstein´s theory of relativity, along with two...

Berkeley Lab Researchers Resolve Controversy Over Gallium Manganese Arsenide that Could Boost Spintronic Performance A long-standing controversy regarding the semiconductor gallium manganese arsenide, one of the most promising materials for spintronic technology, looks to have been resolved. Researchers with the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab)in collaboration with scientist from University of Notre Dame have determined the origin of the...

One More Victory Scored Over Uncertainty In Quantum Physics Measurements

Squeezing what hasn't been squeezed before Most people attempt to reduce the little uncertainties of life by carrying umbrellas on cloudy days, purchasing automobile insurance or hiring inspectors to evaluate homes they might consider purchasing. For scientists, reducing uncertainty is a no less important goal, though in the weird realm of quantum physics, the term has a more specific meaning. For scientists working in quantum physics, the Heisenberg Uncertainty Principle says that...

Dilute magnetic semiconductors (DMS) have recently been a major focus of magnetic semiconductor research. A laboratory from the University of Science and Technology of China explored the feasibility of doping manganese (Mn) into zinc sulfide (ZnS) to obtain magnetic semiconductors. Hideo Ohno and his group at the Tohoku University, Japan, were the first to measure ferromagnetism in transition metal-doped semiconductors such as indium arsenide and gallium arsenide doped with Mn. Ever since,...

Arizona State University researchers are finding ways to improve infrared photodetector technology that is critical to national defense and security systems, as well as used increasingly in commercial applications and consumer products. A significant advance is reported in a recent article in the journal Applied Physics Letters. It details discovery of how infrared photodetection can be done more effectively by using certain materials arranged in specific patterns in atomic-scale...

A team from the National Institute of Standards and Technology (NIST) and the University of Maryland has found an iron-based superconductor that operates at the highest known temperature for a material in its class. The discovery inches iron-based superconductors–valued for their ease of manufacturability and other properties–closer to being useful in many practical applications. Iron-based superconductors, which were discovered only about four years ago, are a hot research...
