Abstract :
Magnetization studies were carried out on Tm2 Fe17-x Cox and Tm2 Fe17-x Alx compounds in the temperature range 4.2 K to 1200 K. Tm2 Fe17 changes its easy axis of magnetization from the basal plane to c-axis below 85 K. This transition occurs at higher temperatures as cobalt or aluminum is substituted for iron. The 
lattice parameter goes through a maximum as a function of x in the Tm2 Fe17-x Cox ternaries. The results are interpreted in terms of distance dependence of the magnetic interactions and a competition between the sublattice magnetic anisotropy. Tm2 Fe3 Co14 has an anisotropy field of 38 kOe and a potential energy product of 43 MGOe at room temperature.
