Dy0.73Tb0.27Fe2 - xCox (x = 0.5, 1.0, 2.0) and their hydrides (hydrogen concentration n = 1.0) are found to crystallize in C15 cubic Laves phase. While the x = 0.5 and 1.0 materials and their hydrides have Curie temperatures above 300 K, the x = 2.0 material and its hydride are paramagnetic at 300 K. The magnetization measurements carried out at 300 K showed large anisotropy and remanence for hydrides of both x = 0.5 and 1.0 and these are found to be further enhanced at 24 K. These results are discussed on the basis of rhombohedral distortions of the crystal lattice. The magnetic moments of the hydrides are found to be less than those of the unhydrided materials.
