Samarium-cobalt magnets are much more powerful than iron magnets. They remain magnetic at high temperatures and so are used in microwave applications. They enabled the miniaturisation of electronic devices.Prior to the 1980s, the best temperature-resistant and energy-dense magnets available were samarium-cobalt (SmCo) based, and could be found in a majority of PM applications (Strnat et al., 1967). However, the Japanese company Sumitomo and the American company General Motors wanted to develop a magnet with good performance ….
