HoAl{sub 2} exhibits a first order spin reorientation transition at 20 K. Heat capacity measurements showed that when Ho is partially replaced by Er in Ho{sub 1-x}Er{sub x}Al{sub 2}, the spin reorientation transition is gradually suppressed, while slowly shifting to higher temperatures with increasing Er concentration. In this paper, we investigate the magnetic properties of pseudo binary Ho{sub 1-x}Er{sub x}Al{sub 2} alloys by ac and dc magnetization measurements. The magnetization data show that the magnetic interactions below T{sub C} are dramatically modified when Er is added in Ho{sub 1-x}Er{sub x}Al{sub 2}. For a better explanation of the experimental data, results of first principles calculations have been presented as well.
