Sm2(Fe,M)17N<i>x</i> compounds and magnets

Abstract

The effect of additives has been studied for the Sm2Fe17Nx compounds. Only Co addition increases the Curie temperature. The Ti, V, or Co additions increase the anisotropy field. The additions of these elements are favorable for the magnet fabrication. The magnet fabrication has been carried out by the Zn metal bonding and mechanical alloying. The (BH)max is 8.7 MGOe and the iHc is 14 kOe for the Zn-bonded magnet. The (BH)max is 10.8 MGOe and the iHc is around 25 kOe for the mechanical alloy magnet.
