   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 ...

   Samarium–cobalt magnet. A samarium–cobalt (SmCo) magnet, a type of rare-earth magnet, is a strong permanent magnet made of two basic elements: samarium and cobalt. They were developed in the early 1960s based on work done by Karl Strnat at Wright-Patterson Air Force Base and Alden Ray at the University of Dayton.

   Programmed magnets, or Polymagnets are magnetic structures that incorporate correlated patterns of magnets with alternating polarity, designed to achieve a desired behavior and deliver stronger local force. By varying the magnetic fields and strengths, different mechanical behaviors can be controlled. Correlated magnet pairs can be programmed ...
