From Phys.org - latest science and technology news stories:
Toshiba Corporation announced today that the company has developed a high-iron concentration samarium-cobalt magnet that is free of dysprosium, a rare earth mineral that is in extremely short supply and increasingly expensive. At typical operating temperatures, the samarium-cobalt magnet has superior magnetic properties to the heat-resistant neodymium magnets currently used in motors.
