AbstractStructure, spin configuration, magnetocrystalline-anisotropy compensation, magnetization, and magnetostriction of TbxHo0.9-xNd0.1(Fe0.8Co0.2)(1.93) (0 <= x <= 0.40) compounds are investigated. A single-phase Laves phase with MgCu2-type structure is synthesized in equilibrium conditions at ambient pressure. The easy magnetization direction (EMD) is observed toward < 111 > axis when x >= 0.25, accompanied by a rhombohedral distortion with large spontaneous magnetostriction coefficients lambda(111). The anisotropy compensation can be achieved by evaluating EMD, magnetization and magnetostriction, and the critical point is realized to be around x = 0.25. The good magnetoelastic properties, e.g., the low anisotropy at room temperature, high polycrystalline saturation magnetostriction (lambda(s) similar to 560 ppm) and large spontaneous magnetostriction coefficient (lambda(111) similar to 850 ppm), are achieved for the Tb0.25Ho0.65Nd0.1 (Fe0.8Co0.2)(1.93) compound, which may make it a promising magnetostrictive material.
