The Nano Materials Research Division at the Korea Institute of Materials Science (KIMS), led by Dr. Tae-Hoon Kim and Dr. Jung-Goo Lee, has successfully developed a groundbreaking grain boundary ...

Permanent magnets used for motors require high energy density, or high levels of magnetism and coercivity. Coercivity is a magnet’s ability to maintain its current level of magnetism, despite exposure ...

Researchers have developed a new class of magnets that does not require rare earths and platinum, yet offers high magnetic strength. Strong magnets are the basis for electric motors, generators, data ...

(Nanowerk News) At just a few atoms of thickness, 2D materials offer revolutionary possibilities for new technologies that are microscopically sized but have the same capabilities as existing machines ...

The origins of magnetic steel can be traced back to the 18 th century when scientists began experimenting with iron alloys. In 1820, Hans Christian Oersted's accidental discovery of electromagnetism ...

March 25, 2014. Researchers from North Carolina State University have found a way to reduce the coercivity of nickel ferrite (NFO) thin films by as much as 80% by patterning the surface of the ...

Researchers from the Department of Energy's Critical Materials Institute (CMI) and Ames National Laboratory have improved the properties of a rare-earth-free permanent magnet material and demonstrated ...
