Alternatively, iron oxide can be mixed with ammonium nitrate ... The resulting α”-Fe 16 N 2 is then separated by magnet and can be formed into solid shapes. This method seems like it would ...

In 1982, two researchers working independently of each other developed the neodymium–iron–boron magnet, which was stronger than any known magnet. It revolutionized the low-cost mass production ...

The University of Tokyo has developed what researchers claim is the world’s smallest nano-magnet. The nano-size ferrite magnet consists of iron oxide. With the material, researches devised a 7.5nm ...

Weaker hard ferrite (iron-oxide) permanent magnets typically max out at around 0.35 tesla. The world's strongest permanent magnets made of neodymium measure around 1.4‑1.6 teslas. Niron’s ...

MPI works by visualizing injected superparamagnetic iron oxide nanoparticles (SPIONs). SPIONs exhibit a nonlinear response to an applied magnetic field: at low fields they respond roughly linearly, ...

Basically, the smaller cube is a super-strong magnet that magnetized the millions of tiny bits of iron oxide in the putty. Once magnetized, the putty tries to distribute itself evenly around the ...

Relatively low magnetic fields can alter the polarization of some pixels composed of iron oxide magnetic particles. However, ...

MP Materials (NYSE: MP) has kicked off commercial production of neodymium-praseodymium metal at its Independence facility in Texas along with trial production of neodymium-iron-boron magnets, the ...
