Abstract
The TbxHo0.75âxPr0.25(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 ã1 1 1ã from the ã1 0 0ã 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 (λ1 1 1) is found to increase with Tb content.
