Injection molded Sm/sub 2/Fe/sub 17/N/sub 3/ anistropic magnet made by using reduction and diffusion method

Sm2Fe1N3 alloy (SFN) is a well known magnet powder expected to be useful for a bonded magnet. Although a long time has passed since SFN magnet was introduced by Coey in 1990[ I], it is far from commercial production unfortunately.
