An international team of physicists that includes a Texas A&M University professor has announced discovery of a new spintronic effect in semiconductor chips, the intrinsic spin Hall effect, which puts a new twist on future technology and the possibility for novel circuits with low energy consumption.
The team is formed by physicists Dr. Jörg Wunderlich and Dr. Bernd Kaestner from the Hitachi Cambridge Laboratory, U.K.; Prof. Tomás Jungwirth from the Institute of Physics of the Academy of Sciences of the Czech Republic and the University of Nottingham, U.K.; and Prof. Jairo Sinova from Texas A&M.
In a normal Hall effect, a voltage is created perpendicular to an electric current as it flows through a conductor in a magnetic field. The magnetic field deflects the moving charges to the sides of the conductor, resulting in an observable Hall voltage.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
