US $100,000 contract supports magnet research
EEC's higher field strength magnets will be useful in developing more powerful communications amplifiers with higher data transmission rates.
Electron Energy Corporation (EEC) has been awarded a US $100,000 Small Business Innovation Research (SBIR) contract by the National Science Foundation (NSF) for Phase I research and development of anisotropic magnet powder coated with iron (Fe) nanoparticles for high-performance nanocomposite magnets.
The contract runs from January through June 2008.
EEC will be supported in this effort by the University of Delaware's Physics Department under the leadership of Dr George Hadjipanayis .
"As a result of this research, we're in the position to develop an entirely new class of magnet materials that have substantially higher magnetic properties than those currently in the marketplace".
"Advances in the performance of magnet materials will enable more compact, lighter weight, less costly electromagnetic devices", said Michael Walmer, EEC President.
Applications for higher field strength magnets are found in spacecraft, microwave components, sensors and commercial systems including computer disk drives, medical imaging, audio systems and motors.
EEC's higher field strength magnets will be useful in developing more powerful communications amplifiers with higher data transmission rates, more available bandwidth and less susceptibility to interference and jamming.
Today, this is especially important as traffic increases on the current internationally recognised transmission frequency bands.
Higher field strength magnet materials will also allow smaller and lighter magnets to be used in these applications, where the smallest reductions in weight and mass translate into significant savings.
In space-based applications, for example, weight reduction can result in savings of over US $100,000 per pound, depending on the space vehicle and launch system.
"EEC's Phase I proposal combines physics, chemistry and metallurgy with a understanding of magnetism at the nanoscale level, which offer new insights to creating nanocomposite powder for permanent magnets with superior properties", said Peter Dent, EEC Director of Sales and Marketing.
For over a decade, researchers predicted the great potential of exchange-coupled nanocomposite magnets, yet have not successfully produced magnets that come close to achieving these properties.
"The innovation of our approach lies in the Fe nanoparticle coating of anisotropic hard magnetic powders that act as a substrate", said Jinfang Liu, PhD, Director of Technology at EEC.
EEC is the only US producer of rare earth magnets and the only company in the world to produce ultra-high-temperature SmCo magnets capable of operating continuously at temperatures up to 550C.
