Abstract
The magnetostrictive characteristics of the melt-spun ribbons of (Tb0.33Fe0.67)1-xBx (x = 0, 0.02, 0.05, 0.1 and 0.15) alloys are investigated as a function of wheel speed during melt-quenching. It is found that the magnetic softness at low fields is improved substantially by the addition of B to the alloys, but the value of λ at 8 kOe obtained for the ribbon quenched at an optimum condition decreases continuously as B content increases from x = 0 (1300 ppm) to x = 0.15 (630 ppm). The present ribbons have a nanocrystalline grain structure even in the as-spun state and exhibit better magnetostrictive characteristics than the bulk and similarly melt-spun ribbons with an additional annealing process.
