The effects of Ni addition on the grain size (D) and coercivity (Hc) were investigated for nanocrystalline (Fe1-xNix)86B14 (x = 0–0.3) alloys prepared by ultra-rapid annealing of melt-spun amorphous precursors. Ni addition resulted in a structural change of the nanocrystallites from bcc to fcc and an exceptionally small D of 4.2 nm was obtained at x = 0.3. Hc was reduced dramatically from 6.8 A/m at x = 0 to as small as 2.6 A/m at x = 0.1. This significant improvement of magnetic softness is well understood by the effect of Ni on the local magnetocrystalline anisotropy. |
