摘要	The magnetic transitions and magnetic and magnetostrictive properties of Tb(x)Dy(1-x)(Fe(0.8)Co(0.2))(2) (0.20 <= x <= 0.40) compounds have been investigated. The spin-reorientation temperature T(SR) decreases from above to below room temperature, when x is increased from 0.25 to 0.40. The easy magnetization direction at room temperature of the Laves phase lies along the < 100 > axis in compounds with 0.20 <= x <= 0.27, while it lies along the < 111 > axis as 0.30 <= x <= 0.40. The magnetocrystalline anisotropy constant K(1) at room temperature reaches a minimum value at x=0.30, indicating it is near the composition for anisotropy compensation. The large polycrystalline saturation magnetostriction lambda(s)approximate to 980 ppm is observed for x=0.30, which can be ascribed to the large magnetostriction coefficients lambda(111) and lambda(100). lambda(100) has a value larger than 600 ppm for the compounds with 0.30 <= x <= 0.35, which can be attributed to the change of the filling of the 3d band due to Co substitution for Fe. Tb(0.30)Dy(0.70)(Fe(0.8)Co(0.2))(2) with a high magnetostriction and a low anisotropy is found to be a good candidate material for magnetostriction applications. A detailed spin configuration diagram for Tb(x)Dy(1-x)(Fe(0.8)Co(0.2))(2) Laves phase around the composition for the anisotropy compensation is given, which should be a guide to develop novel magnetostrictive materials for applications in this series.
