Rotating magnetic moments: Applied Physics Letters reports Bochum's physicists led by Prof. Dr. Hartmut Zabel have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behavior of the spin pumping had previously only been predicted theoretically. The research team at the RUB has now succeeded in measuring the effect using ultrafast X-ray scattering with picosecond resolution. Through their rotation of the magnetic moments, the so-called magnetic...

Computer files that allow us to watch videos, store pictures, and edit all kinds of media formats are nothing else but streams of "0" and "1" digital data, that is, bits and bytes. Modern computing technology is based on our ability to write, store, and retrieve digital information as efficiently as possible. In a computer hard disk, this is achieved in practice by writing information on a thin magnetic layer, where magnetic domains pointing "up" represent a "1" and magnetic domains pointing...

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...

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 dramatic and surprising magnetic effect of light discovered by University of Michigan researchers could lead to solar power without traditional semiconductor-based solar cells. The researchers found a way to make an "optical battery," said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Physics. In the process, they overturned a century-old tenet of physics. "You could stare at the equations of motion all day and you will not...

A newly discovered magnetic phenomenon could accelerate data storage by several orders of magnitude. With a constantly growing flood of information, we are being inundated with increasing quantities of data, which we in turn want to process faster than ever. Oddly, the physical limit to the recording speed of magnetic storage media has remained largely unresearched. In experiments performed on the particle accelerator BESSY II of Helmholtz-Zentrum Berlin, Dutch researchers have now achieved...

Tomorrow's nonvolatile memory devices "“ computer memory that can retain stored information even when not powered "“ will profoundly change electronics, and Cornell University researchers have discovered a new way of measuring and optimizing their performance. Using a very fast oscilloscope, researchers led by Dan Ralph, the Horace White Professor of Physics, and Robert Buhrman, the J.E. Sweet Professor of Applied and Engineering Physics, have figured out how to quantify the...

Nuclear magnetic moment provides a highly sensitive probe into the single-particle structure and serves as a stringent test of nuclear models. In recent decades, the facilities with radioactive ion beam models to study nuclear magnetic moments make it possible to measure the magnetic moments of neutron-rich and proton-rich nuclei with high precision. On the theoretical side, many nuclear structure models, including advanced shell models, and self-consistent mean-field theories, have succeeded...

With the help of neutrons, TUM physicists discover new ways to save data One of the requirements to keep trends in computer technology on track "“ to be ever faster, smaller, and more energy-efficient "“ is faster writing and processing of data. In the Dec. 17 issue of the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the Universitaet zu Koeln report results that could point the way to a solution. TUM physicists set a lattice of magnetic vortices in...
