Stabilizer (B, Co)-free, light rare earth (Pr)-substituted Laves alloys (Tb0.3Dy0.7)1-xPrxFe1.55(0 ≤ x ≤ 0.4) are synthesized, and their structural, magnetic, and magnetostrictive properties are investigated. X-ray diffraction analysis confirms the presence of single cubic Laves phase with an MgCu2-type structure in the (Tb0.3Dy0.7)1-xPrxFe1.55alloys with 0 ≤ x ≤ 0.35. The lattice parameter a of the Laves phase increases, while the Curie temperature decreases, with increasing x from 0 to 0.35. The saturation magnetization of the alloys decreases with increasing x. The linear anisotropic magnetostriction λa(=λ||- λ⊥) shows a maximum of 1502 ppm at x = 0.25 as a result of the magnetocrystalline anisotropy compensation.
