EETimes.com - Cheaper 'supermagnets' could drive future hybrid cars
excerpt:
Now, Northeastern University researchers claim to have invented a
cheap, green, one-step process for creating samarium cobalt permanent
magnets. Cutting the cost of producing the powerful magnets could
usher in a new breed of hybrid automobiles using smaller, cheaper
motors. Space and aircraft applications are also possible.
Lead scientist C.N. Chinnasamy of Northeastern University's Center for
Microwave Magnetic Materials and Integrated Circuits, said samarium
cobalt -- the strongest of the rare earth magnetic materials -- could
be manufactured using recyclable chemicals. The manufacturing process
would be scalable for high-volume production, and magnets could be
built at a fraction of their current cost, Chinnasamy added.

PORTLAND, Ore. — The world's highest temperature superconductors
share an unusual affinity for magnetism, according to researchers in
the U.S. Earlier this month, high-temperature superconducting
iron-compounds with lanthanum and arsenic were separately discovered
by Japanese and Chinese researchers. Now, U.S. researchers have
confirmed those results, heralding a new generation of "supermagnets"
for magnetic-resonance imaging (MRI) machines, superconducting
electric motors, power-generators and -transmission lines.
