Magnetic materials could help build future computers
London, Oct 15 (IANS) Magnetic materials form the basis of most hard disc drives as they are able to store data. Now, a team from the University of Sheffield has proposed that they could also be used to perform calculations and so take on the role of a computer's central processing unit (CPU).
Synthesis of a new lean rare earth permanent magnetic compound superior to Nd2Fe14B
A research group led by Dr. Kazuhiro Hono at the National Institute for Materials Science (NIMS) in Tsukuba, Japan, synthesized a new magnetic compound, which requires a lesser amount of rare earth element than the currently used neodymium iron boron compound. The ratio of neodymium, iron and nitrogen in the new compound, NdFe12N, is 1:12:1. Its neodymium concentration is 17% compared to 27% for ...
How magnetic dimers interact to create long-range order
Researchers carrying out experiments at the U.S. Department of Energy's Advanced Photon Source (APS) and Spallation Neutron Source have shed new light on how magnetic long-range order forms and remains stable despite the presence of disruptive quantum fluctuations. Since the material under study, SrCu2(BO3)2 (SCBO), bears important similarities to layered Cu-O compounds that exhibit high ...
Extremely high-resolution magnetic resonance imaging
For the first time, researchers have succeeded to detect a single hydrogen atom using magnetic resonance imaging, which signifies a huge increase in the technology's spatial resolution. In the future, single-atom MRI could be used to shed new light on protein structures.
