After homogenization and subsequent nitrogenation melt-spun Sm[sub 2]Fe[sub 17]N[sub x] shows high values of coercivity up to 2T. The coercivity was further increased to 2.9T by applying the Zn-bonding technique. Densities up to 6.7 g/cm[sup 3] could be achieved by Hot Isostatic Pressing (HIP). After HIP, however, the Zn-bonded samples show a deterioration in the shape of the demagnetization curves, which is due to the formation of [alpha]-Fe as indicated by X-ray diffractometry.
