Magnet, capable of creating 'room-temperature quantum computers
Recently, a research team at the University of Texas in the United States has successfully developed a quantum computing material that can operate stably at room temperature, exhibiting magnetic strength 100 times greater than pure iron. This groundbreaking achievement overcomes the reliance on ultra-low temperature

Designing a dysprosium-free high-performance neodymium magnet
Fujitsu Limited today announced that, in joint research with the National Institute for Materials Science (NIMS) and Fujitsu Laboratories Ltd., it has developed the world's largest magnetic-reversal simulator, using a mesh covering more than 300 million micro-regions.
Prospects for the use of NdFeB materials: helping the humanoid robot industry usher in an explosion
1. Characteristics and application of NdFeB materials As the third-generation rare earth permanent magnet material, NdFeB has the characteristics of small size, light weight and strong magnetism, and is known as the "magnet king" in the industry. Its excellent performance makes it play a key role in the production process of 3C consumer electronics, home appliances, new energy vehicles and wind power industries. In the field of humanoid robots, NdFeB is mainly used in the manufacture of servo motors. The servo motor is the core component to realize the precise con
You probably know that magnets attract specific metals and they have north and south poles. Opposite poles attract each other while like poles repel each other. Magnetic and electrical fields are related, and magnetism, along with gravity and strong and weak atomic forces, is one of the
Permanent magnets help optimize geometry of future fusion reactor
According to reports, Michael Zarnstorff (Michael Zarnstorff) of the Max Planck Princeton Plasma Physics Research Center in New Jersey was helping his son with a science fair project (he wanted to build a rail gun). Realized that neodymium boron magnets are now powerful enough to be used in place of superconducting coils. Saalsdorf's team's conceptual design combines simple toroidal superconducting coils with flat magnets attached to the outside of the plasma vacuum vessel. Just like a refrigerator magnet, only sticks to one side, creating a magnetic field mainly inside the cont
Three-dimensional coercivity control by local diffusion in sintered NdFeB magnets
JL MAG is the world`s largest and first CO2-neutral producer of sintered neodymium-iron-boron (NdFeB) magnets with its headquarters in Ganzhou, China. The start of huge volume demanding projects for the electrification of automobiles has increased demand for NdFeB magnets, which ha
The development of sintered NdFeB magnets delivered the strongest magnet materials with the highest room-temperature magnetic field (remanence) and demagnetisation resistance (coercivity). The associated success story includes numerous applications with higher efficiencies due to higher power density and even applications that could only be enabled through the use of NdFeB. The biggest applications in terms of demand are wind turbine generators and traction machines for automotive. Traction machines contain o
Price increases affecting industry
The large price increase of 2011, caused by reductions in China`s exports of rare earth elements, forced the magnet industry to focus on the reduction of heavy rare earth usage. After these reduction developments, many applications still use NdFeB, but no longer need the heavy rare earth elements. The coercivity was enhanced, e.g., by grain size reduction after pulverisation, or by metallurgical additives. Nevertheless, the high operating temperatures of traction machines which can be in the range of 140-200
The best solution for locally applied coercivity
Coming back to the fact that diffusion magnets are always inhomogeneous, a question arises as to how to turn this into an advantage. The magnetic circuit does not need a homogenous material. Applications need a magnet that has a sufficiently high local coercivity at each position inside the magnet. Excessive coercivity can be a disadvantage and can lead to locally reduced remanence. In addition, there is no physical reason why high-field concentrations should appear inside a magnet. The field density in
the potential outcome still depends on the specification. Specifying the magnet as consisting of several zones, with specific homogenous coercivity requirements, is an initial challenge. This is a compromise enabling the standard IEC 60404-5 on cut-off specimens to be utilised. The largest potential is obtained by a real, three-dimensional profile of heavy rare earths and coercivity for the respective zones. Magnet us
New quantum magnet unleashes electronics potential
Some of our most important everyday items, like computers, medical equipment, stereos, generators, and more, work because of magnets. We know what happens when computers become more powerful, but what might be possible if magnets became more versatile? What if one could change a physical property that defined their usability? What innovation might that catalyze? It`s a question that MIT Plasma Science and Fusion Center (PSFC) res

Scientists have discovered that trapping light within certain magnetic materials can significantly enhance their intrinsic properties. Their study examined a specific layered magnet capable of hosting powerful excitons, enabling it to trap light independently. The optical reactions of this material to magnetic occurrences are remarkably stronger than those in regular magnets.
