Physicists at the U.S. Department of Energy’s Ames Laboratory compared similar materials and returned to a long-established rule of electron movement in their quest to explain the phenomenon of extremely large magnetoresistance (XMR), in which the application of a magnetic field to a material results in a remarkably large change in electrical resistance. It is a useful property, which could be used in the development of computers with increased processor speeds and data storage.

Researchers at the U.S. Department of Energy’s Ames Laboratory have developed germanium nanoparticles with improved photoluminescence, making them potentially better materials for solar cells and imaging probes. The research team found that by adding tin to the nanoparticle’s germanium core, its lattice structure better matched the lattice structure of the cadmium-sulfide coating which allows the particles to absorb more light.
11/20/2017Two projects funded by the Critical Materials Institute, a U.S. Department of Energy Energy Innovation Hub, were selected as R&D 100 Award winning technologies. Winners of the 2017 awards were announced Friday, Nov. 17 at the R&D Conference in Orlando, Fla. In total, DOE projects garnered 33 R&D 100 Awards.The two CMI funded projects were:
The U.S. Department of Energy’s Ames Laboratory has discovered and described the existence of a unique disordered electron spin state in a metal that may provide a unique pathway to finding and studying frustrated magnets.
Condensed matter physicists use the term “frustrated” to describe a kind of magnet in which the spins fail to align into stable magnetic order. In perfectly frustrated magnets called spin liquids, the disordered magnetism of these materials persists even at very low temperatures, and their unique properties are of interest in the development of quantum computing
