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

Name: Work Video:
Duration: 3 min 30 s
Description: Sm2Fe17N3, alloy (SFN) is a well known magnet powder expected to be useful for a bonded magnet[1]. Besides the magnetization is as high as that of Nd2Fe14B alloy, both the uni-axial anisotropy and the Curie temperature are higher than those of it. As a result, it is possible to obtain high coercivity after just milling the alloy and also possible to obtain high energy product in a bonded magnet.
