Abstract
The structure and magnetic properties of the melt-spun ribbons of Tb 0.27Dy 0.73Fe x alloy are investigated as a function of various wheel speeds during melt-quenching using a single-roll technique. It is found that Tb 0.27Dy 0.73Fe x alloy is difficult to be fabricated as amorphous state by using the melt-quenching method. X-ray diffractions show that all these ribbons for x=1.7−2.0 are the MgCu 2-type phase at the wheel speed of 45 m s −1. For Tb 0.27Dy 0.73Fe x alloy, the high wheel speed is beneficial to eliminate the RFe 3 phase and form the perfect MgCu 2-type phase. Compared with the bulk of Tb 0.27Dy 0.73Fe 1.95, these ribbons exhibit higher intrinsic coercivity value and their saturation magnetizations increase as well. The magnetostriction of Tb 0.27Dy 0.73Fe 1.95 composite with 4% epoxy resin is 640×10 −6 at 900 kA m −1.
