The saturation remanence and coercivity are figures of merit for hard magnets, although maximum energy product is also commonly quoted. The 1980s saw the development of rare-earth magnets with high energy products but undesirably low Curie temperatures. Since the 1990s new exchange spring hard magnets with high coercivities have been developed ...
Ferrofluid on glass, with a rare-earth magnet underneath. A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements.Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.
On May 24, 2024, the Biden Administration announced a 25 percent tariff on rare earth magnets from China, set to take effect in 2026. This marks the first time that critical minerals, including rare earth magnets, have been specifically included in the tariffs. [53] Following the tariffs MP Materials put out a statement listing the tariffs.
A U.K.-based company announced last week that they’d successfully developed, in just three months, a magnet that doesn’t use rare earth metals at all using AI—according to the company, that ...
Canonical single-molecule magnets are the so-called Mn 12 and Fe 8 systems, with 12 and 8 transition metal atoms each and both with spin 10 (S = 10) ground states. The phenomenon of zero field magnetization requires three conditions: A ground state with finite spin; A magnetic anisotropy energy barrier; Long spin relaxation time.
