Abstract

Saturation magnetizations were measured on single crystals of TbFe2, DyFe2, Tb0.27Dy0.73Fe2and TmFe2. Over most of the temperature rang from 4 K to 300 K, these values are substantially larger than those measured earlier on polycrystals. The intrinsic magnetic anisotropies, K1(0)\´s, as determined from magnetic fields required for saturation, are huge ( $\\sim5 \\times 10^{8}$ erg/ cm³). For these highly magnetostrictive compounds, the magnetoelastic contribution to the anisotropy $-frac{1}{2}c_{44}\\lambda \\min{111}\\max {2}$ is a significant fraction of the total anisotropy.
