摘要	Structure, spin configuration and magnetostriction of Tb0.4-xNdxDy0.6(Fe0.8Co0.2)(1.93) (0 <= x <= 0.30) compounds are investigated. A single-phase Laves phase is synthesized at equilibrium conditions at ambient pressure for the indicated Nd-concentration range. Direct experimental evidence for magnetocrystalline-anisotropy compensation between Tb3+ and Nd3+ is obtained by performing X-ray diffraction on magnetic-field aligned powders and by evaluating the easy magnetization direction and the magnetostriction. A large polycrystalline saturation magnetostriction lambda(S) (similar to 1170 ppm) is observed for x=0.05, which can be attributed to the large magnetostriction coefficients lambda(111) (similar to 1600 ppm) and lambda(100) (similar to 520 Ppm). The compound Tb0.35Nd0.05Dy0.6(Fe0.8Co0.2)(1.93) with large magnetostriction and low anisotropy is found to be a good candidate material for magnetostriction applications. (C) 2014 Elsevier B.V.
