Abstract

Dy_1-xPr_x(Fe_0.35Co_0.55B_0.1)₂ (0≤x≤1) Laves compounds with a cubic MgCu₂-type structure were synthesized by arc melting and subsequent annealing. The lattice parameter of the Laves compounds linearly increases, while the Curie temperature T_c decreases with increasing Pr content. The saturation magnetization M₅ at 5 K or 295 K for the Dy_1-xPr_x(Fe_0.35Co_0.55B_0.1)₂ alloys decreases to reach a minimum, then increases with increasing Pr content. The composition for magnetic moment compensation is about x=0.55 at 295 K and x=0.65 at 5 K, respectively. The magnetostriction λ_║ or λ_˔ at room temperature was investigated either parallel or perpendicular to the applied field using a standard strain gauge technique.
