The Introduction ofsamarium colbalt

a type of rare earth magnet, is a strong permanent magnet made of an alloy of samarium and cobalt. They were developed in the early1970s by Albert Gale and Dilip K. Das of Raytheon Corporation.[1]They are generally ranked similarly in strength to neodymium magnets,[2]but have higher temperature ratings and higher coercivity. They are brittle, and prone to cracking and chipping. Samarium-cobalt magnets have maximum energy products (BHmax) that range from 16 megagauss-oersteds (MGOe) to 33 MGOe, that is approx. 128 kJ/m3to 264 kJ/m3; their theoretical limit is 34 MGOe, about 272 kJ/m3. They are available in two "series", namely Series 1:5 and Series 2:17.

Sintered Samarium Cobalt magnets exhibit magnetic anisotropy, meaning they can only be magnetized in the axis of their magnetic orientation. This is done by aligning the crystal structure of the material during the manufacturing process.Performance for samarium cobalt magnets:
