Innovative process allows creation of stable ferromagnetic materials at room temperature in fewer steps than before Scientists at the University of Massachusetts Amherst report that for the first time they have designed a much simpler method of preparing ordered magnetic materials than ever before, by coupling magnetic properties to nanostructure formation at low temperatures. The innovative process allows them to create room-temperature ferromagnetic materials that are stable for long...

Neutron Analysis Reveals Unique Atom-scale Behavior Of 'Cobalt Blue'
2011-09-07 05:55:07

  Neutron scattering studies of "cobalt blue," a compound prized by artists for its lustrous blue hue, are revealing unique magnetic characteristics that could answer questions about mysterious properties in other materials. Experiments at the Spallation Neutron Source (SNS) and High Flux Isotope Reactor (HFIR), both located at the Department of Energy's Oak Ridge National Laboratory, indicate novel behaviors in the antiferromagnetic material cobalt aluminum oxide, -- CoAl2O4, or...

Scientists have found opal-like crystals in the Tagish Lake meteorite, which fell to Earth in Canada in 2000. This is the first extraterrestrial discovery of these unusual crystals, which may have formed in the primordial cloud of dust that produced the sun and planets of our solar system 4.6 billion years ago, according to a report in the Journal of the American Chemical Society. Katsuo Tsukamoto and colleagues say that colloidal crystals such as opals, which form as an orderly array of...

"The nation that controls magnetism will control the universe," famed fictional detective Dick Tracy predicted back in 1935. Probably an overstatement, but there's little doubt the nation that leads the development of advanced magnetoelectronic or "spintronic" devices is going to have a serious leg-up on its Information Age competition. A smaller, faster and cheaper way to store and transfer information is the spintronic grand prize and a key to winning this prize is understanding and...

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...

The work could lead to improved methodologies for creating materials by design Scientists have given us a plethora of new materials "“ all created by combining individual elements under varying temperatures and other conditions. But to tweak an intermetallic compound even more, in order to give it the attributes you desire, you have to go deeper and re-arrange individual atoms. It's a process similar to what bioengineers employ when they add and delete genes to create synthetic...

It's not hard to argue in favor of alternatives to fossil fuels these days, but one popular argument "“ domestic energy security "“ may be standing on very shaky legs. A lot of rare metals are needed to make photovoltaic panels, rare earth magnets for wind generators, fuel cells and high-capacity batteries for hybrid and electric vehicles. But most industrialized nations, including the United States, are almost entirely dependent on foreign sources for those metals. The only way...

Cobalt is a chemical element in the periodic table that has the symbol Co and atomic number 27. Notable characteristics Cobalt is a hard ferromagnetic silver-white element. The Curie temperature is of 1388 K with 1.6~1.7 Bohr magnetons per atom. It is frequently associated with nickel, and both are characteristic ingredients of meteoric iron. Mammals require small amounts of cobalt salts. Cobalt-60, an artificially produced radioactive isotope of cobalt, is an important radioactive...

Limonite Limonite is a ferric hydrate of varying composition, the generic formula is frequently written as FeO(OH)·nH2O, although this is not entirely accurate as Limonite often contains a varying amount of oxide compared to hydroxide. Together with hematite, it is mined as ore for the production of iron. Limonite is heavy and yellowish-brown. It is not a true mineral, however, but a mixture of similar hydrated iron oxide minerals, mostly Goethite. Limonite forms mostly in or near...

Magnetite is a magnetic mineral form of both iron(II) oxide and iron(III) oxide or (iron(II,III) oxide), with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. Magnetite is the most magnetic of all the minerals on Earth, and these magnetic properties led to lodestone being used as an early form of magnetic compass. Small grains of magnetite occur in almost all igneous rocks and metamorphic rocks as well as many sedimentary rocks. Magnetite is a...
