Abstract :
The magnetostriction of melt-spun ribbons of the alloys (R0.33Fe0.67)1-xBx (R=Tb0.3Dy0.7 and 0⩽x⩽0.06) is investigated as a function of wheel speed during melt-quenching. The low field sensitivity of magnetostriction with magnetic field is found to be good for the alloys with x⩽0.04 over a wide range of wheel speed. This magnetostrictive behavior is in contrast with that observed previously for Dy-Fe and Tb-Fe based alloys and is thought to be due to low intrinsic magnetocrystalline anisotropy of the compound
