Structural and intrinsic magnetic characteristics of Tm/sub 2-//sub x/ Dy/sub x/ Fe/sub 14/ B (for the entire range of composition) and Tm/sub 2/ Fe/sub 14-//sub x/ Co/sub x/ B (for x up to 4) were investigated in detail between 4.2 K and their Curie temperatures. Progressive replacement of Tm by Dy enhances the anisotropy field H/sub A/ markedly. This was evidenced from the expansion of the uniaxial anisotropy temperature range determined by constructing the magnetic-phase diagram. These results are found to be in very good agreement with the crystal field theory, employing the second-order terms. Addition of Co in the lattice improves the magnetic ordering temperature, but reduces the saturation magnetization.
