Abstract
The effect of nitrogen insertion on the structural and magnetic properties of (Sm1.5Gd0.5)Fe17−xCox compounds has been investigated. X‐ray powder diffraction analysis shows that all the nitrides are single phase and crystallize in the Th2Zn17‐type structure. The lattice parameters of the (Sm/Gd)2Fe17−xCoxNy compounds increase with increasing x. Magnetization studies indicate that all the samples are ferromagnetic at room temperature. Nitrogen insertion leads to an increase in the Curie temperature Tc from 520 K for Sm1.5Gd0.5Fe16Co to 880 K for Sm1.5Gd0.5Fe16CoN2.9. Moreover, the nitrogen insertion increases the saturated magnetization Ms. Ms increases from 107.67 emu/g for x = 0 to 149.92 emu/g for y = 3. X‐ray diffraction measurements on magnetically aligned powder samples of Sm1.5Gd0.5Fe17−xCoxNy reveal a change in the easy magnetization direction from planar to conical after nitrogen insertion.
