context_page_description: A samarium–cobalt 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 and Alden Ray at Wright-Patterson Air Force Base and the University of Dayton, respectively. In particular, Strnat and Ray developed the first formulation of SmCo₅.
  They are generally ranked similarly in strength to neodymium magnets, but have higher temperature ratings and higher coercivity.
context_section_description: Fender used one of designer Bill Lawrence's Samarium Cobalt Noiseless series of electric guitar pickups in Fender's Vintage Hot Rod '57 Stratocaster. These pickups were used in American Deluxe Series Guitars and Basses from 2004 until early 2010.
  In the mid-1980s some expensive headphones such as the Ross RE-278 used Samarium Cobalt "Super Magnet" transducers.
  Other uses include:
  High-end electric motors used in the more competitive classes in slotcar racing
  Turbomachinery
  Traveling-wave tube field magnets
  Applications that will require the system to function at cryogenic temperatures or very hot temperatures (over 180 °C)
  Applications in which performance is required to be consistent with temperature change
  Benchtop NMR spectrometers
  Rotary encoders where it performs the function of magnetic actuator
