Scientist works to understand how fluctuations change biochemical reactions inside us We are surrounded by a constantly changing magnetic field, be it the Earth's or those emanating from devices, such as cell phones. Carlos Martino, an assistant professor at the University of Nevada, Reno, is interested in understanding how these magnetic-field fluctuations change biochemical reactions inside us. Martino explains that the subject is controversial. "Our research shows that exposure to...

Magnetic Fields Can Send Particles To Infinity
2012-04-17 13:34:38

Researchers from the Complutense University of Madrid (UCM, Spain) have mathematically shown that particles charged in a magnetic field can escape into infinity without ever stopping. One of the conditions is that the field is generated by current loops situated on the same plane. At the moment this is a theoretical mathematical study, but two researchers from UCM have recently proved that, in certain conditions, magnetic fields can send particles to infinity, according to the study...

The ability to detect and respond to magnetic fields is not usually associated with living things. Yet some organisms, including some bacteria and various migratory animals, do respond to magnetic fields. In migratory animals like fish, birds, and turtles, this behavior involves small magnetic particles in the nervous system. However, how these particles form and what they are actually doing is not fully understood. In a new study, published February 28 in the online, open-access journal...

New physical phenomenon could drastically reduce energy consumption by computers Three years ago Professor Christian Pfleiderer and his team from the physics department at the TUM discovered an entirely new magnetic structure in a silicon manganese crystal — a grid of magnetic eddies. Together with the team of Professor Achim Rosch from the University of Cologne, he studied the properties of these eddies, so-called skyrmions, named after the British physicist Tony Skyrme, who...

An international team of scientists has demonstrated a revolutionary new way of magnetic recording which will allow information to be processed hundreds of times faster than by current hard drive technology. The researchers found they could record information using only heat - a previously unimaginable scenario. They believe this discovery will not only make future magnetic recording devices faster, but more energy-efficient too. The results of the research, which was led by the...

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...
