摘要：
The TbxHo0.75-xPr0.25(Fe0.9B0.1)(2) (x = 0, 0.1, 0.15, 0.2, 0.25, and 0.3) compounds are found to stabilize in a cubic Laves phase structure. The lattice parameter, magnetostriction (at 10 kOe), and Curie temperature are found to increase with increasing Tb content. The compound with x 0.15 exhibits a possible anisotropy compensation between the Tb and (Ho/Pr) sublattices. The easy magnetization direction rotates towards the < 1 1 1 > from the < 1 0 0 > direction, with increasing Tb content. The splitting of the (4 4 0) peak accompanied by the spontaneous magnetostriction-induced rhombohedral distortion is observed for compounds with x >= 0.15 and the spontaneous magnetostriction <lambda(1 1 1)> is found to increase with Tb content.
