NdFeB magnet:
Neodymium magnet, also known as NdFeB magnet, Neo magnet, permanent magnet, rare earth magnet, is a tetragonal crystal formed by neodymium, iron, and boron (Nd2Fe14B).
Due to different manufacturing processes, NdFeB magnets can be divided into sintered NdFeB and bonded NdFeB. Bonding is actually injection molding, while sintering is vacuumed and heated at high temperature.In 1982, Masayoshi Sagawa of Sumitomo Special Metals discovered neodymium magnets. The magnetic energy product (BHmax) of this kind of magnet is greater than that of the samarium cobalt magnet, and it was the material with the largest magnetic energy product in the world at that time. Later, Sumitomo Special Metals successfully developed the powder metallurgy process, and General Motors successfully developed the spin-blown smelting method to prepare neodymium magnets. This kind of magnet is the strongest permanent magnet today, and it is also the most commonly used rare earth magnet.
NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools.In order to avoid corrosion damage, it is necessary to do a protective treatment on the surface of the permanent magnetic material during use, such as electroplating with gold, nickel, zinc, tin, and spraying epoxy resin on the surface.Neodymium is a metal that magnetically orders only below 19 K (−254.2 °C; −425.5 °F), where it develops complex antiferromagnetic orders. However, compounds of neodymium with transition metals such as iron can order ferromagnetically with Curie temperatures well above room temperature, and these are used to make neodymium magnets.The strength of neodymium magnets is the result of several factors. The most important is that the tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA ≈ 7 T - magnetic field strength H in units of A/m versus magnetic moment in A·m2). This means a crystal of the material preferentially magnetizes along a specific crystal axis but is very difficult to magnetize in other directions. Like other magnets, the neodymium magnet alloy is composed of microcrystalline grains which are aligned in a powerful magnetic field during manufacture so their magnetic axes all point in the same direction. The resistance of the crystal lattice to turning its direction of magnetization gives the compound a very high coercivity, or resistance to being demagnetized
