Abstract
At temperatures below 200 K the demagnetization curves of Zn-bonded Sm2Fe17Nx magnets show a dip indicating different types of ferromagnetic particles in the material. The coercivity decreases more rapidly with increasing temperature than the anisotropy field. The shape of demagnetization curves and the coercivity can be improved by sieving the milled powder. The internal magnetization processes are a combination of nucleation of easily movable domain walls and single-domain-particle processes
