| Abstract | The spin configuration and magnetostrictive properties of TbxDy0.7-xPr0.3(Fe0.9B0.1)(1.93) (0.10 <= x <= 0.28) Laves compounds are investigated. The spin phase diagram for the compounds is constructed to illustrate both the composition dependence of the Curie point T-C and spin reorientation temperature T-SR and the arrangement for the easy magnetization direction (EMD). It is found that when x is increased from 0.16 to 0.28, T-C increases from 617 to 623 K, while T-SR decreases from 375 to 160 K at which the EMD reorients from < 100 > to < 111 > axis. The magnetization and magnetostriction of the compounds are measured as a function of applied field. The magnetocrystalline anisotropy constant K-1 and the ratio lambda(a)/K-1 reach a minimum and a maximum value at x=0.22, respectively. The single phase Tb0.22Dy0.48Pr0.3(Fe0.9B0.1)(1.93) compound has the lowest magnetocrystalline anisotropy, the highest magnetostriction to anisotropy ratio, and a large spontaneous magnetostriction lambda(111) of similar to 1500 ppm at room temperature. In view of these properties, the compound is a promising magnetostrictive material.
