Structure and Magnetostriction of Tb_0.7Pr_0.3Fe_X Prepared by Solid-State Synthesis

Abstract:

Mechanical alloying (MA) was used to prepare pseudobinary high Pr-content Tb_0.7Pr_0.3Fe_x alloys. The structural and magnetoelastic properties were in investigated by means of x-ray diffraction and a standard strain technique. A single (Tb,Pr)Fe₂ Laves phase with MgCu₂-type structure for the composition Tb_0.7Pr_0.3Fe_1.80 was synthesized by MA and subsequent annealing process. The high magnetostriction of 600 ppm was achieved at 10 kOe for the epoxy-bonded Tb_0.7Pr_0.3Fe_1.8 composite.
