  2. Neodymium magnet - Wikipedia

    en.wikipedia.org/wiki/Neodymium_magnet

    Inventor Masato Sagawa demonstrating a NdFeB magnet's force with 2 kg bottle. A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet.

  3. Ferrite (magnet) - Wikipedia

    en.wikipedia.org/wiki/Ferrite_(magnet)

    Ferrite (magnet) A stack of ferrite magnets, with magnetic household items stuck to it. A ferrite is one of a family of iron oxide -containing magnetic ceramic materials. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetized to become permanent magnets. Unlike many ferromagnetic materials, most ferrites are ...

  4. Alnico - Wikipedia

    en.wikipedia.org/wiki/Alnico

    Alnico is a family of iron alloys which, in addition to iron are composed primarily of aluminium (Al), nickel (Ni), and cobalt (Co), hence the acronym [1] al-ni-co. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, and are used to make permanent magnets. Before the development of rare-earth magnets in the 1970s ...

  5. Rare-earth magnet - Wikipedia

    en.wikipedia.org/wiki/Rare-earth_magnet

    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. The magnetic field typically produced by rare-earth ...

  6. Magnetic 2D materials - Wikipedia

    en.wikipedia.org/wiki/Magnetic_2D_materials

    Magnetic van der Waals materials is a new addition to the growing list of 2d materials.The special feature of these new materials is that they exhibit a magnetic ground state, either antiferromagnetic or ferromagnetic, when they are thinned down to very few sheets or even one layer of materials.

  7. Single-molecule magnet - Wikipedia

    en.wikipedia.org/wiki/Single-molecule_magnet

    A single-molecule magnet (SMM) is a metal-organic compound that has superparamagnetic behavior below a certain blocking temperature at the molecular scale. In this temperature range, an SMM exhibits magnetic hysteresis of purely molecular origin. [1][2] In contrast to conventional bulk magnets and molecule-based magnets, collective long-range ...
