Spintronics: Scientists find new magic in magnetic material
From powerful computers to super-sensitive medical and environmental detectors that are faster, smaller and use less energy—yes, we want them, but how do we get them?

(Phys.org) —Researchers at the Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used ...
(Phys.org) —A team of researchers from the Royal Institute of Technology, Stockholm, the University of Maryland, and the NIST Center for Nanoscale Science and Technology have measured large variations in ...
(Phys.org)—Although researchers know that a large portion of the brain is devoted to visual processing, exactly how we interpret the complex patterns within natural scenes is far from understood. One question ...
The fact that an ultrashort laser pulse is capable of demagnetizing a ferromagnetic layer in a jiffy has been well-known since approximately 1996. What we don't yet understand, however, is how exactly this demagnetization ...
(Phys.org)—Magnetism may be one of the most fundamental concepts in physics, but under the surface, magnetism holds complex secrets that scientists are still trying to unravel. One of these areas involves ...
Researchers have demonstrated theoretically that oscillation of 5–140 GHz is possible by supplying direct current to a ferromagnetic nanocontact device.
At microscopic scales, magnetic materials are full of structure. Tiny magnets, called domains, order themselves in ways that control the magnetic properties of the bulk material. Technologies such as hard ...
(Phys.org)—Scientists at the Naval Research Laboratory have demonstrated that graphene, a single layer of carbon atoms in a honeycomb lattice, can serve as a low resistance spin-polarized tunnel barrier ...
(Phys.org)—Spintronic technology, in which data is processed on the basis of electron "spin" rather than charge, promises to revolutionize the computing industry with smaller, faster and more energy efficient ...
(Phys.org)—Scientists from TU Berlin, DESY and the University of Paris discovered a surprising effect in the demagnetisation of ferromagnetic materials at DESY's free-electron laser FLASH. The team of researchers ...
(Phys.org)—A team of researchers from the NIST Center for Nanoscale Science and Technology, the Royal Institute of Technology, Stockholm, and the University of Maryland have demonstrated a microscopy method ...
The spin Hall effect (SHE) enables us to create spin current in non-magnetic materials without using ferromagnetic materials. It is a crucial element in the central idea behind spintronics, that of manipulating ...
RIKEN and the National Institute for Materials Science (NIMS) have succeeded in forming a skyrmion crystal in which electron spin is aligned in a vortex shape in a microdevice using the helimagnet FeGe. The ...
Minimal evidence of a Higgs transition 1 of north and south poles of electron spins was observed in a magnet Yb2Ti2O7 at the absolute temperature 2 0.21 K. A fractionalization of these monopoles from electron ...
