Abstract

High Pr-content Tb_1-xPr_x(Fe_0.4Co_0.6)_1.9 magnetostrictive alloys (0.7 ≤ x ≤ 1.0) with a single cubic Laves phase have been synthesized by melt-spinning and subsequent annealing processes. The lattice parameter and the magnetization of the Tb_1-xPr_x(Fe_0.4Co_0.6)_1.9 Laves phase increase while the Curie temperature, the magnetocrystalline anisotropy, and the spontaneous magnetostriction coefficient λ_{1 1 1} decrease with increasing Pr-content. The characteristic of the magnetostriction λ_a = λ_{{norm of matrix}} - λ_⊥ of the epoxy/Tb_1-xPr_x(Fe_0.4Co_0.6)_1.9 composites can be well understood by the spontaneous magnetostriction λ_{1 1 1} and the magnetocrystalline anisotropy of the Tb_1-xPr_x(Fe_0.4Co_0.6)_1.9 alloys. The epoxy/Pr(Fe_0.4Co_0.6)_1.9 composite free of high-cost Tb has a high magnetostriction of about 500 ppm at 6 kOe, suggesting that it would be a promising magnetostrictive composite material for low field application.
