摘要

The structural, magnetic and magnetostrictive properties of TbxHo0.9-xNd0.1Fe1.93 (0 for x = 0.10 to for x = 0.25 through an intermediate direction around x = 0.15, subjected to the anisotropy compensation between Tb3+ and Ho3+ ions. The splitting of (440) XRD peak accompanied by the spontaneous magnetostriction-induced rhombohedral distortion is observed for the compounds of x >= 0.2, and the spontaneous magnetostriction coefficient Am is found to increase with increasing Tb content. The analysis of XRD, EMD, magnetization and magnetostriction shows that the pseudobinary system TbxHo0.9-xNd0.1Fe1.93 is an anisotropy compensation system and the compensation point is realized around x = 0.25. The Nd-containing Tb0.25Ho0.65Nd0.1Fe1.93 Laves-phase compound has good magnetostrictive properties, that is, a large saturation magnetostriction (lambda s similar to 585 ppm) and a low magnetocrystalline anisotropy at room temperature, which may make it technological interest for magnetostriction applications.
