摘要	High Pr-content Tb1-xPrx(Fe0.4Co0.6)(1.9) magneto strictive 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 Tb1-xPrx(Fe0.4Co0.6)(1.9) Laves phase increase while the Curie temperature, the magnetocrystalline anisotropy, and the spontaneous magnetostriction coefficient X-111 decrease with increasing Pr-content. The characteristic of the magnetostriction lambda(a) = lambda(parallel to) - lambda(perpendicular to) of the epoxy/Th1-xPrx(Fe0.4Co0.6)(1.9) composites can be well understood by the spontaneous magnetostriction lambda(111) and the magnetocrystalline anisotropy of the Tb1-xPrx(Fe0.4Co0.6)(1.9) alloys. The epoxy/Pr(Fe0.4Co0.6)(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.
