Abstract
The structural and magnetic properties of Tb0.1 Ho 0.9-x Prx (Fe0.9 B0.1)2 (x=0, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, and 0.4) compounds are investigated. The compounds with 0≤x≤0.25 are found to stabilize in single cubic Laves phase structures. Small quantities of the (Tb,Ho,Pr)2 Fe14 B phase and rare-earth phases for x0.3 and also the (Tb,Ho,Pr) (Fe,B)3 phase for x0.35 are observed along with the Laves phase. The saturation magnetization and Curie temperature are found to decrease with Pr content. However, the magnetostriction (at 10 kOe) is found to increase with Pr content. The x=0.15 compound is found to exhibit a possible anisotropy compensation between the (TbHo) and Pr sublattices. The easy magnetization direction (EMD) is found to rotate toward 〈113〉 as the Pr content increases, up to x=0.25, and for x0.35 there is a tendency for the EMD to shift toward 〈111〉. © 2008 American Institute of Physics.
