Quantum Spin Liquid Is A New State Of Magnetism
2012-12-21 09:38:33

redOrbit Staff & Wire Reports - Your Universe Online While experts had previously only confirmed the existence of two states of magnetism, experts from the Massachusetts Institute of Technology (MIT) report that they have been able to experimentally demonstrate the existence of a third kind. The MIT researchers have dubbed the new state a quantum spin liquid (QSL), and they describe their findings in this week's edition of the journal Nature. It joins ferromagnetism (the simple form...

Earth's Magnetic Field And Maori Stones
2012-12-09 06:12:00

April Flowers for redOrbit.com - Your Universe Online The Maori of New Zealand have been cooking in earth ovens, called hangi or umu, since at least the 1200s. These ovens are fire pits, scooped out of the ground. A fire is built and large volcanic stones are laid over the fire. When the fire burns down, the food is wrapped in leaves, placed in baskets and laid on the rocks with wet fern fronds. A layer of earth is scraped over the food, sealing in the heat and steam. The stones inside...

The Road To Spintronics Advances
2012-10-15 13:23:39

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 data storage and processing. Materials drawing a lot of attention for spintronic applications are dilute magnetic semiconductors — normal semiconductors to which a small amount of magnetic atoms is added to make them ferromagnetic. Understanding the source of ferromagnetism in...

New Experience In Nanodisk Magnetic Vortices

Berkeley Lab Researchers Take a Mesocale Look at Magnetic Vortex Formations The phenomenon in ferromagnetic nanodisks of magnetic vortices — hurricanes of magnetism only a few atoms across — has generated intense interest in the high-tech community because of the potential application of these vortices in non-volatile Random Access Memory (RAM) data storage systems. New findings from scientists at the U.S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory...

Successful imaging of individual atoms and associated electric fields in ferroelectrics could lead the way to a new era of advanced electronics As scientists learn to manipulate little-understood nanoscale materials, they are laying the foundation for a future of more compact, efficient, and innovative devices. In research to be published online July 8 in the journal Nature Materials, scientists at the U.S. Department of Energy's Brookhaven National Laboratory, Lawrence Berkeley National...

Imperial scientists take an important step in developing a material using nano-sized magnets that could lead to new electronic devices Scientists have taken an important step forward in developing a new material using nano-sized magnets that could ultimately lead to new types of electronic devices, with greater processing capacity than is currently feasible, in a study published today in the journal Science. Many modern data storage devices, like hard disk drives, rely on the ability to...

Nature Communications: New development for fast storage media An international team of researchers from Germany and the Netherlands has developed a new material for storage media. For the first time they enable the switching of so called spin currents at room temperature in a vertical magnetic field. This increases the storage density distinctly. The novel switches can be used, for example, as read heads in future hard discs or as bits in non-volatile random access memory devices (MRAM)....

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...

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,...

Dr. Ariando of the National University of Singapore discovered a collective electronic state not seen before in the bulk of either 2 individual insulating oxides, thus demonstrating that electrons at their interface can now exhibit ferromagnetism In many ionic materials, including the oxides, surfaces created along specific directions can become electrically charged. By the same token, such electronic charging, or 'polarization', can also occur at the interface of two connecting materials....

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
