9] Tsutsui H et al found Samarium-Cobalt
magnet to be superior in magnetic properties to other magnets.
have developed a new high-iron concentration samarium-cobalt
magnet that is free of heavy rare earth elements, highly resistant to demagnetization, and that achieves significantly superior magnetic properties at high temperatures to the heat-resistant neodymium magnets currently used in motors.
(SmCo) magnets were developed in the 1960s and 1970s.
(SmCo) magnets have the highest known resistance to demagnetization.
For higher temperatures, a special samarium-cobalt
material may be specified.
Almost all existing electric traction motors employ permanent magnets made from materials such as neodymium-iron-boron and samarium-cobalt
Lockheed Martin's Spy-1 radar on Aegis destroyers contains samarium-cobalt
magnets that will need to be replaced over the 35-year lifespan of the radar.
Used magnetic materials are: Samarium-Cobalt
and Neodymium-Iron-Boron, which combine high flux density (beyond 1 T) and very large coercive force (up to 7000 A/cm).
It uses rare-earth alloys of Nd-Fe-B and samarium-cobalt
When the disc-shaped superconductor of yttrium-barium-copper oxide was cooled to -321 [degrees] F, it generated repulsive forces that levitated a rotor made of the permanent magnet alloy, samarium-cobalt
Rare Earth (RE) magnets, such as samarium-cobalt
, find use in Atomic Energy, Space and Defence industries for a variety of strategic and non-strategic applications.
