Laboratories where he worked from 1972 to 1982. Without his supervisor's support for the new magnetic compound, Sagawa resigned in 1981, and then joined Sumitomo Special Metals. Within several months after joining Sumitomo Special Metals in 1982, the strongest sintered NdFeB magnet was developed. Dr. Sagawa presented the new discovery of NdFeB magnet during the Magnetism and Magnetic Materials Conference in Nov. 1983 in Pittsburgh, Pennsylvania. In 1988, Sagawa founded Intermetallics, a research and development company devoted to the development of
